I started off by applying online on their website. Then, received an email for a phone interview, two of them. 45 minutes each with a 15 minute break in between. I gladly scheduled for a date and time.
The first interviewer was pretty cool, but I struggled with the question, there was not enough time to complete a implementation of a function (longest path in a tree). I answered all his previous questions with ease though.
The second interviewer also asked an algorithm question, which was about sorting numbers in two separate arrays. I thought I did pretty good, since I answered them correctly and gave optimal solutions. I explained every step of thinking and any alternative solutions. You should be able to go through your thought process well.
Know your Big-Oh notation and algorithms before you do the interview. There aren't really "trick" questions, but just tough questions.
I didn't hear back for two weeks, so I followed up. Surprisingly, I got email asking if I was interested in Fall internship position rather then Summer. But I have school, so I couldn't take it. Then, I got a email couple days later saying they needed interns in Toronto, Canada and asked if I was interested. I said yes, since I've visited Toronto before and wouldn't mind working there.
They prepared everything fast and even made the visa application process easy for me. The recruiter wasn't that fast in responding, but the second one is efficient. I really liked their hiring process.
