First, there was a 15 minute chat with the recruiter. Then, a 30 minute zoom with the hiring manager. After that, a 1.5 hour technical interview where I had to implement a connection pool in an IDE. This was followed by a 1.5 hour design interview, where I walked through a past design and answered a system design question. Lastly, there was an hr interview.

The HR team was super communicative throughout the process, keeping me updated on all the necessary steps. Even though I didn't pass the first interview, they were kind enough to see if another role might be a better fit and continued with that instead.

Coding Technical
I applied for a Senior Software Engineer position and went through 4 interviews. In the last interview, they told me I wasn't eligible for the senior role because I apparently lacked sufficient experience, claiming only those with over 10 years at the company qualify as seniors, which is false. When I inquired about an engineering ladder to assess qualifications, they seemed unfamiliar with the concept. I'm not interested in working there anymore; they interviewed me for a senior role and then stated it wasn't senior, plus they don't even have an engineering ladder, which is absurd.
