I applied online. The process took 4 weeks. I interviewed at FTI Consulting (New York, NY) in Sept 2021
Interview
Had 2 rounds and a final round with the senior director. It was more behavioral. The people interviewing were incredibly nice and welcoming.
Questions asked: why this firm, what sparked your interest in consulting, tell me about a time you used survey. (Some more questions that are follow up based on resume and what has been previously said)
For the AC
1) group round - did a case study and each of us were asked questions based on our group answer after
2) math and verbal reasoning test, written essay test
3) individual interviews - one with current analysts about cv, one with a partner (casing)
Pretty basic behavioral questions - no technicals. I'd recommend knowing your "why" and being able to clearly explain your interest in the specific practice. Also, prepare to ask the interviewer more in-depth questions, too.
Online assessment including verbal and numerical parts for the financial and economic consulting intern position. Given one minute for each question, I insist the time was quite tight for verbal part
