Applied for the Senior BA position a while back.
The interview took place in 2 phases.
First round with HR, around 30 min discussion. Very nice, very polite, very inviting.
Second round - tech related interview with the CTO.
It was challenging for me, but still they had a very respectful attitude. Helping me answer those questions that were more difficult for me.
They called me a couple days later with their response. Even though my application was rejected, this was still a pleasant experience, one that I learned from.
