I've had 3 interviews with a company applying to replace a lead developer of a team of 7 that specializes in making tumblr themes. The first Interview was a casual sit down, which at the end of they gave me an assignment to complete by the end of the week- If completed I would receive a second interview. I completed it within 3 hours, and sent it to them. I got contacted for a second interview which would be a several hour sit down interview in which I had to produce code in front of their developers. Everything went swimmingly well, and I was invited for yet another interview. This was another casual interview in front of a panel of developers, and we all seemed to mesh together very well. They all mentioned that they were impressed with my level of understanding and my lack of redundancies within my code. At the end of this interview they mentioned they would contact me on friday regarding if I got the job or not. Friday past... I did not receive any email or phone call, so i emailed them asking if they had made a decision. No response. I emailed them again today (four days later) , once again inquiring if they had reached a decision. And I've yet to get a reply.
The only part of the interview that seemed a bit weird was when they inquired about my age. I'm 20 years old and they are all in their late 20's which they all seemed very uneasy at (I think mostly because I just look older then I actually am)... Other then that, my skill level is up to par with their developer's, if not better and we all got along together very well.
Are there any steps I can take now that might improve my chance to get a response? Could this have to do with Tumblr being sold?
