Hi Anonymous,

I would structure the answer to this question as follows:

  1. Say which is a "good" weakness, that is, a weakness which is neither a red flag for consulting nor a point of strength presented as a weakness;
  2. Say what you are doing to improve on it, giving a concrete example (eg, don’t simply say “I am working on it”, but rather “I am doing XYZ and ABC in order to get better at this”).

Too competitive may be perceived as a red flag – you need to be a team player in consulting. Taking too much responsibility seems instead a point of strength presented as a weakness.

The best way to find a “good” weakness is to avoid standard ones such as public speaking. Rather, go through the following approach to identify real weaknesses:

  1. Write down a list of all your weaknesses
  2. Eliminate those who are red flags in consulting (all those you may not be able to change quickly or ever – eg no strong education background/ relevant experience - or clear problems in consulting – eg missing deadlines, poor communication with teammates, not being on time)
  3. Think of how you could improve for the ones remaining. Select the best three and apply the previous structure

This allows to have “natural” weaknesses which show personal improvement.

For more help on the typical behavioural questions asked in consulting interviews please feel free to PM me.

!. Create a list of your weaknesses. Be honest.

2. Cross out "red flags" weaknesses for consultant (bad with numbers, low stress resistance, etc.)

3. Cross out weaknesses that makes you look like you promoting yourself (perfectionist, too responsible, etc.)

4. Cross out weaknesses that are irrelevant for consulting job (can't make myself to go to gym, afraid to perform on big stages, etc.)

5. From the rest options, pick the ones where you can show that you work on it. It's important to show that you not only know your weaknesses, but you doing specific actions to improve it.

6. Try your answer on case partner/ coach. Correct it if needed.

Please ignore all the bullsh*t advice you can find in typical interview preparation books! Just reflect and come up with a REAL weakness. Explain it to the interviewer (ideally with a little anecdote that illustrates it), and then outline how you are working on it and how you intend to further improve going forward. That's it! What you need to demonstrate is the ability to self-reflect. Coming up with a fake answer will do nothing but sabotage yourself.

Cheers, Sidi

The most important thing I can tell you is this: be honest. Don't go in there and blurt out a "fake weakness" like a lot of people try to do. For example, when people say they work too hard or that they are too much of a perfectionist. Having interviewed people myself before (disclaimer: for non-consulting jobs), when candidates would do this it would just make me cringe.

It is OK to show that you are human, to talk about what your real weaknesses may be. That being said, because this is an interview, it is also important to show that you are actively trying to overcome your weaknesses on a day to day basis. My advice here would be to be ready to provide in-depth examples of ways in which you are addressing your weaknesses every day and the progress you have made so far.

In my humble opinion, making progress on a real weakness and showing commitment to change is much more powerful than appearing to be perfect.

While it is important to be honest, you should, at the very least, avoid mentioning characterisitcs that are vital in the industry field as your weaknesses. If you apply for consulting roles, do not say you have poor communication skills, or you hate numbers. You may risk leaving a negative first impression even though you manage to explain how you try to improve afterwards.

Hope it helps!
