LinkedIn Developer interview questions

Applied in first week of Jan 2016, Got initial screening call from recruiter after 3-4 days only. After that she setup first technical phone interview with two interviewers. It contains introduction, resume discussion followed by two technical coding algorithms/data structures questions. After 4 days I heard back from them and they want to setup second interview round. It is the same like previous one with two interviewers only and same type of coding questions. After all, I had to wait for a long time as they took a long time to give me an offer after final interview. I got offer after 1 month of second/final interview.
