First two phone interviews were straight forward, fun, informative and not tough in any real way. The third interview was on-site, all day - 6 hrs. Met with mostly managers and one SDET sandwiched in between. Started with bright personalities in the beginning and ended sort of flat. One system design question, one algorithms question, and lots of testing related questions. The algorithm question was standard, however I struggled to connect with that interviewer as he seemed to focus narrowly on finding errors instead of also discovering knowledge. We failed to establish a mutual understanding of the situation. There were tons of testing questions and they all shared a specific mindset and approach to testing. After a while it was pretty exhausting and in some cases I struggled to fight the fatigue in repeating verbal answers- last interviewer seemed tired and unamused... too bad I didn't jump up and make it interactive with the white board, ha. Overall it was an good learning experience personally even though I was unable to demonstrate I was a match for their needs. From what I can tell, it's a nice place for a developer to work, learn, and grow- In particular, I sensed that there's a lot of room for improvement in architecture and "modernization" - which - actually, would be real fun to play a part in renovating.
