I turned in my resume at a career fair on campus. When I was talking with the recruiter at the career fair, I was asked to do some coding. Then I was contacted by a recruiter a week later. I had 4 interviews in total and they were all on campus. My first interview was mostly theory questions about stacks, heaps, processes, and threads. I was also asked to do a simple coding problem too. That evening I received an email saying I passed the first round and they'd like me to come back 2 days later for 3 more interviews. The interview questions were quite challenging. I don't think I did very well at the second interview, which was writing a code that takes a float and output a string representing a price in the format $xx,xxx.xx. I managed to produce a working piece of code but with a lot of help from the interviewer so I think if you're stuck, you should ask for hints and they don't mind it. I was more successful at the third interview in which I was asked solve two problems, again the programming language was my choice. The last round was different from the previous three. I was given a problem and was asked to describe an algorithm to solve it. No coding required. In fact when I started to write down some code I was reminded that I only need to describe the algorithm. Optimization was a big deal because I was asked to analyze running time of my code and to optimize them, especially at the last round. After the last round, I was asked if I need to know their decision by any specific time. I said I'd like to know their decision before then end of the year. The interviewer smiled and said it wouldn't take that long. Typically it'd take 2-3 weeks. That's why I was so surprised and excited when I got an email from them later that day announcing I was offered the position. So basically it took less than 4 days for the entire process.
