3 stage interview, first two stages went well, personal chat and then a technical chat, all seemed to be going fine. Was a bit worried by the age demographic as there was no developers in the company under the age of 35..
The third stage was a technical challenge, it seemed very old fashioned, almost as if the questions were designed to catch you out. Very maths based which was not made clear in two previous interviews.
I didn't want to leave a negative review as the guys seems like nice guys, but I did not hear anything after this interview, no feedback at all. Assuming it was a no.
