Hi Anonymous,
fit part and cases are similar to the standard ones in face-to-face interviews. Preparation should then cover the following:
Fit
You should prepare the standard questions on leadership, drive, impact, teamwork plus questions about the firm; thus at the bear minimum the following, using a STAR or PARADE structure for the answer:
Case
Standard 30-minute case, as in face-to-face interview (profitability, M&A, market entry etc). It may be slightly easier to get a market sizing case, as this is simpler to deliver and follow over the phone.
Additional tips
Below you can find some additional suggestions:
# 1. Go the extra mile in the case when presenting what you think. This is important in face-to-face interview, but even more in phone interviews where the interviewer cannot see you or your notes. In short, this implies:
# 2. Attach to the wall in front of you all the material you need (structures, tips for fit part, etc) – in this way you do not have to look for information on the go
# 3. Prepare your own questions. One thing many candidates neglect to do at this stage is to prepare their own questions. Relevant questions at the end are a great way to show your interest in the company and get additional points. In the first reply at the following post you can find some more information on the ideal type of questions to ask at the end of your call: https://www.preplounge.com/en/consulting-forum/open-house-at-bcg-311
# 4. Dress properly - as if you had a face-to-face interview
# 5. Prepare the place for the call - good internet connection and quite environment are must-have
# 6. Smile – although you are over the phone, smiles are perceived by people as well, and show positive attitude
Hope this helps,
Francesco
