I interviewed with Aisera in 2018. The interview process span across 2 weeks. I had an initial screening call from a senior technical person, then came onsite and talked to 5 senior engineers. The quality of the team seemed very high and they were very professional. I was also given a take home exercise of an interesting algorithmic problem which shows that they are looking for smart people that go beyond their specific duties and knowledge. I enjoyed the problem given to me and I spent my weekend trying to solve it.
