reached out to discuss a number of opportunities, at first the HR person was eager to speak to me. We had an initial conversation about my experience and she referred me to a person internally to chat with. I followed up twice and never heard back from her! I think it's really bad practice not to reply when you have asked someone to take time to interview.

Recruiter is nice and he/she would give you a preparation before each round of interviews. There were around 5 rounds of interview which were a little bit excessive since I was not applying for a senior position. It will be great to shorten the interview to speed up the process.
