I had 1 screening round and then 3 back to back same-day rounds. The 30 min screening was a shallow dive into one of my resume projects and then a short case study on classification modeling. The subsequent 3 rounds were resume grilling, behvioral and live coding respectively. The resume grill was a deep dive into a research project and then follow up questions on applications, the behvaioral round involved a set of non-conventional questions (like how would you ask a senior/colleague for help, how do you use AI based tools in your work, etc) and live coding was implementing a 2D conv operation. These 3 rounds were 45 mins each. The entire process took 2 weeks.
