I applied through college or university. The process took 1 day. I interviewed at LinkedIn
Interview
Got selected through campus recruiting and had my first phone interview. The interviewer seemed like he was not interested at all, and did not communicate well during the interview. There were two programming questions, and the rest were behavioral questions.
One of the questions was about working with certain set of numbers..and when I asked what to assume (-ves, rational numbers, etc), he said "just assume the basic ones.." and did not bother to explain what this meant.
I applied online. The process took 4 weeks. I interviewed at LinkedIn in Jan 2013
Interview
Applied through the LinkedIn website and was contacted by a recruiter via email for setting up the initial phone screen. Phone screen was usual, why did you select computer science, tell us about yourself a little, which field I was interested in working so they could select the appropriate team.
First round went well, consisted of one coding question and some machine learning concepts. Was contacted a week later and was set up for 2 back to back phone interviews. Second round was similar to the first, a coding question and some more machine learning concepts. Third round was all about complexity and Big O analysis, nothing too hard.
Overall, a very good learning experience even though I didn't make it.
Interview questions [1]
Question 1
There was no unexpected question as such. One of them involved searching in a matrix sorted row wise. The other one involved finding the exponent of a number in an efficient manner. I figured the exponentiation by squaring method and wrote the pseudo code for that which was correct. All in all, nothing unexpected and the questions can be answered with a little bit of practice.
