First recuriter called me and then a few weeks later hiring manager called me to ask for an on-site interview. The interview lasted 4,5 hours and met with 4 engineers and 1 manager. The most part of interview is technical. And engineers are very nice and respectful expect one is asking very trivial but tricky questions. In general, the people there are easy going. The downside is low salary comapred to other comanies.

Interview process was pretty straight forward starting with telephonic round followed by onsite interviews. Onsite interviews consisted of 5 1/2 hrs interviews. All the team was pretty co-operative and helped me to get to the answer.
