I applied through college or university. I interviewed at Informatica
Interview
On campus interview with their technical director (I think). He went through several data structure questions and asked me to write a piece of code. In the code questions I've given the right answer but he asked for an optimization, unfortunately there is actually no where to optimize (since the tables are sorted). He suggested to use hash table, but I was confused and not pointing out that it won't be an optimization. So they never contacted me afterwards.
