Last Updated on February 9, 2024

When you finally show up for your case interview with McKinsey, BCG, and Bain, you don’t want anything to be left to chance. Apart from the skills you display in the case interview and the fit interview, it is all about your appearance and preparedness on the big interview day. These interviews are not just about showcasing your analytical prowess and problem-solving skills; they encapsulate the entirety of your professional persona, from knowledge and experience to appearance and interpersonal abilities.

We cover both in the following article, which is based on an excerpt from the book: The 1%: Conquer Your Consulting Case Interview.

Appearance is an important aspect for management consultants. Next time you walk around the airport, look around. You can usually spot them a mile away with their tailored outfits and Rimowa or Tumi carry-ons, usually rushing through the airports like there is no tomorrow. Once hired, you represent the legacy of your firm at the client site.

Hence, it is equally important to look the part when you go through the interview process. When walking into top-tier consulting interviews, you do not want anything to be left to chance.

Importance of First Impressions

First impressions are pivotal. Within the first few moments of your interview, evaluators form an initial perception based on your appearance and demeanor. This assessment, albeit subconscious, can significantly influence the remainder of your interaction. Consulting firms, known for their meticulous attention to detail and high expectations, view candidates’ ability to present themselves professionally as a direct reflection of their potential to represent the firm in front of clients.

In the high-stakes environment of consulting, your appearance acts as a non-verbal communicator of your professionalism, attention to detail, and respect for the firm’s culture. It signals your understanding of the industry’s standards and your readiness to be part of a realm where excellence is not just appreciated but expected. The adage “dress for the job you want, not the job you have” holds particularly true here, underscoring the importance of dressing appropriately as a fundamental component of your interview preparation.

Thus, as you prepare to step into consulting interviews, remember that your skills and intellect are as crucial as the image you project. A well-considered attire not only enhances your confidence but also complements your capabilities, setting the stage for a successful first impression that paves the way for a fruitful discussion about your future with the firm.

Consulting firms are still relatively conservative organizations dealing with serious matters of large client organizations. Just fifteen years ago, it was frowned upon for a male consultant to wear dark brown leather shoes, a McKinsey partner once told me; only black leather shoes were considered appropriate. Luckily, times are changing, and formal rules and attitudes have become more relaxed. Still, it’s best to overdress for the occasion.

Securing a position at a top consulting firm demands more than just intellectual rigor and strategic acumen; it requires an understanding of the professional image these firms expect. The dress code for consulting interviews is steeped in tradition, emphasizing conservatism and meticulous grooming as reflections of the professionalism and precision consultants must bring to their client engagements.

Dressing for Success: Men’s Guide

For men, the cornerstone of interview attire is the suit. Opt for a classic, well-fitted suit in navy blue, charcoal, or dark grey. These colors convey professionalism and versatility. Pair your suit with a crisp, white or light blue shirt, ensuring it is neatly pressed and fits well.

A conservative tie is essential, adding a touch of personality while maintaining professionalism. Patterns should be minimal, leaning towards simple stripes or solids that complement your suit and shirt.

Footwear should be equally considered, with polished leather dress shoes in black or dark brown as the preferred choice. Ensure your belt matches the color of your shoes, tying your ensemble together.

Dressing for Success: Women’s Guide

Women have a bit more flexibility in their choices but should still aim for conservative professionalism. A well-tailored pantsuit or skirt suit in neutral tones such as navy, black, or grey is appropriate. If opting for a skirt, ensure it is of a modest length, typically knee-length or slightly longer.

Blouses should be simple and elegant, in subtle colors that complement your suit. Avoid overly bright colors or intricate patterns that could distract.

Footwear should be professional and comfortable. Closed-toe flats or heels with a moderate height are best, ensuring you can move confidently and comfortably throughout the day.

Key Pieces and Accessories

Accessories should be chosen with a mindset of complementing rather than dominating your outfit. For men, a simple, elegant watch and a leather belt matching your shoes can round off your attire nicely. Women can consider modest jewelry, like a simple necklace or stud earrings, and a watch or bracelet that doesn’t overwhelm the outfit.

Both men and women should ensure that any bags or portfolios they bring match the professional tone of their attire, avoiding overly casual or sporty designs.

The goal of your interview attire is not to make a bold fashion statement but to present yourself as a polished, professional candidate who understands the culture and expectations of the consulting world. Dressing appropriately for your consulting interview respects the firm’s professional standards and demonstrates your keenness to be part of their esteemed team.

Principles of Choosing Your Interview Attire

Navigating the nuances of interview attire in the consulting world requires more than just selecting the right colors or brands; it involves understanding the principles that guide these choices. Here are four key principles to consider when choosing your outfit for a consulting interview:

  1. You want to feel comfortable. Some live interview rounds last from 9 a.m. to 5 p.m. Choose something you feel comfortable in looks-wise but also fit-wise.
  2. Keep it subtle and classy. Keep your statement pieces at home. Stick to classic darker colors for suits, and brighter white or light blue colors for shirts and blouses. Avoid complex patterns. Choose a classic tie and a limited number of subtle accessories.
  3. Wear clothes in the right size. You do not need to get a tailored piece but avoid clothes that are either too big or too small for you.
  4. If in doubt, overdress rather than underdress.

Comfort and Fit

Your interview day could span several hours, making comfort and fit paramount. Clothes that fit well not only enhance your appearance but also allow you to focus on the interview itself rather than adjusting your outfit. Choose fabrics that breathe well and attire that fits your form without being restrictive, ensuring you can sit, stand, and move comfortably throughout the day.

Subtlety and Class

Consulting firms appreciate subtlety and class in attire. Your outfit should underscore your professionalism and attention to detail without overshadowing your skills and qualifications. Opt for classic styles and neutral colors that convey sophistication. Loud patterns, bright colors, and flashy accessories can be distracting and may send the wrong message about your judgment and fit with the firm’s culture.

Sizing Matters

An outfit that fits perfectly speaks volumes about your attention to detail—a critical skill in consulting. Too tight and you’ll seem uncomfortable and possibly unprofessional; too loose, and you may appear unkempt or indifferent about your appearance. If off-the-rack clothing doesn’t fit just right, consider having your outfit tailored. This doesn’t mean every piece must be custom-made, but adjustments can ensure a polished, personalized fit that enhances your confidence and poise.

When in Doubt, Overdress

The adage “it’s better to be overdressed than underdressed” holds especially true in consulting interviews. If you’re uncertain about the dress code, err on the side of formality. Overdressing slightly demonstrates your seriousness about the opportunity and respect for the firm. It’s much easier to subtly dial down a too-formal outfit (for instance, by removing a tie or jacket) than to try and elevate an overly casual look in a professional setting.

Incorporating these principles into your attire selection process will help ensure you present yourself as a capable, polished candidate ready to tackle the challenges of the consulting world. Remember, the goal is to make a positive, lasting impression that complements your skills and experiences, positioning you as the ideal candidate for the role.

Clarifying Dress Code with HR

If you find yourself uncertain about the expected dress code for your consulting interview, reaching out to Human Resources (HR) for clarification is a prudent step. This not only shows your attention to detail and proactive approach but also ensures you align perfectly with the firm’s expectations, avoiding any potential missteps on the day of your interview.

How to Approach HR for Dress Code Clarification

  • Be Professional: Frame your inquiry in a professional manner, emphasizing your desire to present yourself in the best possible light for your upcoming interview.
  • Specific Questions: Instead of a broad query about what to wear, consider asking if the firm has a specific dress code for interviews or if there are any attire recommendations they can provide.
  • Timing: Reach out well in advance of your interview date. This gives you ample time to prepare and, if necessary, make any adjustments to your planned attire.

Benefits of Clarifying Dress Code with HR

  • Confidence: Knowing you’re dressed appropriately for the interview context can significantly boost your confidence, allowing you to focus on articulating your qualifications and fit for the role.
  • First Impressions: Adhering to the firm’s dress code contributes to making a positive first impression, demonstrating respect for the firm’s culture and an understanding of professional norms in consulting.
  • Avoiding Overthinking: Getting clarity on dress code expectations removes one potential source of stress or overthinking, enabling you to concentrate on the more substantive aspects of your interview preparation.

Beyond Dress Code: Other Appearance Considerations

While selecting the right interview attire is crucial, other aspects of your appearance also play a significant role in making a strong first impression. Grooming and personal care are equally important and should complement your carefully chosen outfit, showcasing your professionalism and attention to detail.

Grooming Tips for Men

  • Hair: Keep your hair well-groomed and styled neatly. If you have long hair, consider tying it back to maintain a polished look. A fresh haircut a few days before the interview can also enhance your appearance.
  • Facial Hair: If you wear a beard or mustache, ensure it’s neatly trimmed. Clean-shaven is often preferred for its universally professional appearance, but well-maintained facial hair can also be acceptable in today’s professional settings.
  • Nails: Clean and trim your nails. This small detail can make a significant difference in your overall presentation.
  • Scent: Opt for a light, fresh scent or none at all. Strong colognes can be overpowering in close quarters and may not be well-received by everyone.

Tips for Women

  • Makeup: Aim for a natural, polished look with makeup. Overdoing it can distract from your professional appearance. Use makeup to enhance your features subtly rather than make a bold statement.
  • Hair: Your hairstyle should reflect the overall professional tone of your attire. Whether you choose to wear your hair up or down, ensure it looks neat and tidy.
  • Nails: Like with men, clean, well-manicured nails are a must. Opt for neutral polish colors or a clear coat to maintain a professional look.
  • Perfume: If you choose to wear perfume, ensure it’s light and not overwhelming. As with men, the key is subtlety.

Final Touches Before the Interview

  • Review Your Appearance: Take a moment to review your appearance in full before leaving for the interview. Ensure your clothes are wrinkle-free, your shoes are polished, and there are no last-minute stains or issues with your attire.
  • Carry Essentials: Have a small kit handy for last-minute adjustments or emergencies. This could include items like a lint roller, breath mints, a small comb or brush, and a stain remover pen.
  • Mind Your Posture: Your posture can significantly impact your overall appearance. Stand tall and confident, with shoulders back and head held high. This not only improves how you’re perceived but can also help boost your confidence. If the interview is in person, have a firm handshake when introducing yourself to the interviewer.
  • Consider Final Tweaks: Brush your teeth, take a mint, take a shower, and use deodorant beforehand. You will sweat a lot during the interviews. Avoid chewing gum during the interview.

What to Bring to Your On-site Interviews

Arriving at your on-site interviews well-prepared extends beyond dressing appropriately and ensuring your grooming is impeccable. It’s also about what you bring with you. Having the right items on hand can not only ease your nerves but also demonstrate your organizational skills and foresight. Here’s a list of essentials that will help you navigate the interview day smoothly.

  • Printed Copies of Your Resume: Even though your interviewers will likely have a digital copy, bringing several printed copies of your resume shows preparedness. It also ensures you have a backup in case of unexpected requests. For many firms, this is not essential.
  • Notepad and Pen: A sleek notepad and a professional-looking pen are essential for jotting down notes, questions you might want to ask, or insights shared during the interview. It’s a subtle way to show you’re engaged and value the information being discussed. Top firms will usually give you their own paper and pens and collect them again after the end of the interview.
  • Identification and Necessary Documents: Some buildings and organizations require a form of ID for entry. Ensure you have this, along with any other documents specified by HR, such as completed application forms or references.
  • Breath Mints or Gum: Fresh breath is a small but crucial detail, especially in the close quarters of an interview room. Have breath mints or gum on hand, but remember to dispose of them before your interview begins.
  • Directions and Contact Information: Have the interview location and any necessary contact information easily accessible. Arriving on time is critical, and knowing whom to contact in case of an unforeseen delay can alleviate stress.
  • A Functional Watch: Keeping track of time is important, especially if you have back-to-back interviews or need to manage parking. A watch can be a practical accessory, allowing you to discreetly monitor the time without appearing to check your phone.

Attire and Preparation for Virtual Interviews

In the era of remote work, virtual interviews for consulting jobs have become commonplace. However, the standards for professionalism and preparedness remain high:

  • Dress Formally: Even though the interview is virtual, dress as you would for an in-person meeting. This not only impacts how you’re perceived by the interviewer but can also influence your mindset and performance.
  • Test Your Technology: Ensure your internet connection is stable, your webcam and microphone are working, and your lighting is flattering. Do a trial run with a friend or family member to troubleshoot any issues.
  • Create a Professional Background: Choose a quiet, well-lit space with a neutral background. Minimize potential distractions for both you and the interviewer.
  • Have Materials Ready: Keep a notepad, pen, and your resume nearby. Prepare any frameworks or notes you may need to reference during case discussions, ensuring they’re out of camera view but easily accessible.

Checklist for Interview Day

To ensure nothing is overlooked, here’s a checklist to help you prepare for the case interview, whether it’s in-person or virtual:

  • Review Your Resume: Be ready to discuss any aspect of your resume in detail, drawing connections between your experiences and the qualities consulting firms value.
  • Master the Case Structuring and Frameworks: Familiarize yourself with techniques to break down problems and brainstorm solutions.
  • Practice Mental Math: Consulting cases often require quick, accurate calculations. Sharpen your mental math skills and practice with relevant exercises.
  • Learn Chart and Exhibit Interpretation: Find ways to quickly derive insights from charts and tables.
  • Prepare for the Fit Interview: Structure answers and stories for the most common fit and behavioral interview questions.
  • Prepare Questions for the Interviewer: Have insightful questions ready to ask at the end of the interview. This shows your interest in the role and the firm.
  • Get a Good Night’s Sleep: Rest is crucial. A clear, alert mind will serve you far better than cramming until the early hours.
  • Set Up Your Interview Space: For virtual interviews, finalize your setup the day before. For in-person interviews, organize your documents and essentials.
  • Plan Your Route: If the interview is on-site, plan how you’ll get there and allow extra time for unexpected delays.
