2 on the phone informational interviews. 1 final round
Somewhat casual for the phone interviews, mostly fit questions. expect technicals/questions about basic financial accounting to be thrown in.
For the final round, its an inperson interview/online if not close to their HQ. 3 rounds where you'll first meet with the analysts, followed by a more technical round where you'll meet with the PM's, last round is meeting with the executive VP (pretty much conversational)
