Three rounds of interviews, including a final round interview. The final round interview was in-person and included a panel of 5 or 6 people (~3hrs). Timed Excel test as well early on in the interview process.
Not too difficult! They asked basic profit/statement questions. I would say more focused on your interests/qualitative assessments. As long as you know your basic IB prep you should be fine.
I applied through an employee referral. I interviewed at RA Capital Advisors
Interview
Got the first-round phone interview after doing the informational call with an analyst. Two analysts interviewed me during the phone interview. I was not prepared even though the interview is easy.
