Technical Coding
I applied through LinkedIn for a .Net senior Software Engineer position. After a mobile screening, I attended three rounds of technical interviews over four weeks. I never heard back from the team, which I found unprofessional given the time I invested. I even reached out, but there was no reply or rejection email.

Technical Coding Behavioral
For the Core Data team specifically, the interview process included an initial Hackerrank assessment followed by three more rounds. These rounds covered Backend (Java), Frontend, and a Manager interview. My experience was positive all the way to the end. The team members were friendly, and their enthusiasm for the role and their responsibilities was clear when they spoke about it. It seems like a good place to develop professionally.

So the interview process is like this. First, you get a take-home assignment. Then, there's an initial screening with some basic tech questions. After that, you go through 3 tech interviews, followed by an interview with the team or department lead. Finally, there's an office visit. If you're quick, you might get all these done in a single week. The interviewers were developers from various teams and locations.
