It was a valuable experience, and I went through many processes, learning a lot along the way. This has equipped me with knowledge and confidence that will better prepare me for the upcoming interviews ahead.
The process started with completing a written assessment that involved questions related to what ML projects you have worked on and what are you expecting in your next role. Following it, there was a phone screen with the technical recruiter and then a technical interview with the hiring manager.

I submitted the resume online and HR contacted me on the same day I submitted it, which is the fastest reply within all the companies. First-round is the Hr call, and the second one is OA. Hiring manager and Hr are very nice.
