Technical Technical Presentation Behavioral
It was a 3 round process. First round was basic ML and some guesstimates. Second round had 2 puzzles, I could solve one completely and the other one partially but my approach was correct and the interviewer liked it. Final round was about my projects and some HR questions.

Technical Coding
It was great, but I wasn't ready for my resume, so I kind of messed up there. The interview was pretty simple and mostly about my resume, with some basic AI knowledge and a few puzzles thrown in.

Behavioral Technical Coding System Design Case Presentation
I applied through an employee referral, and the whole process took about 2 months. It started with a 45-minute phone interview with a Senior Recruiter. Then, there was a 45-minute video interview with an Operations Manager. After that, I had four technical interviews, each lasting an hour, with Senior Data Scientists and a Senior Data Science Manager. The last interview was a 1-hour combined technical and experience-based interview with the Chief Data Scientist. The technical interviews usually covered three parts: questions about my resume, scenario-based machine learning questions, and brain teasers.
