Software Engineer Interview

Redwood City, CA

I applied through college or university and the process took a day - interviewed at Informatica in November 2013.

Interview Details – There is one round on campus interview. Took 45 minutes. Two simple questions about binary tree traverse and string duplications.

Then there is one day onsite interview. About 5 round totally, each is one hour. No break between interviews (except the lunch). So its a tough day. The questions including design, algorithm, test case, brain teaser...

Software Engineer

I applied through college or university and interviewed at Informatica.

Interview Details – 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.

I applied online and interviewed at Informatica.

Interview Details – 2 rounds phone were all algorithms. Basically not hard.
Onsite was all about multi-threading. They will go into very detail coding about multithreaded patterns. please be prepared for common patterns.
algorithm questions were quit basic, like tree traverse, sort, graph search. design questions were not hard either. please refresh your memory for common design patterns of OOAD. Java and C++ are both their primary language. you can choose either and helpful to have both.
2 rounds were introduction to 2 different team by their director/manager. One for cloud and hadoop is very fun.

Interview Question – weighted bipartite matching. I guess it's just for fun....implement reader/writer lock with different priority preferences.   Answer Question
