2 phone interviews(coding+problem solving skill)+on-site. Coding test is just SQL and Python, very interactive experience. For Problem solving interview, be sure you study the material the recruiter sent, very helpful instruction. On-site is 5 hours including lunch, almost everyone asks about AB testing, seems to be a heavy part of their daily job and interviewing criteria. One this made me a bit surprising and disappointing is the onsite tech/coding session. The lady asked me the exact same question as my phone tech interview, so I basically just repeat my answers again, and she told me that she is not familiar with python. I explained my code to her but she didnt quite understand, I can feel she is really not familiar with the syntax. And then she made a conclusion that my code doesnt work, and asked me to stop explaining. It is possible that I did not do a good job explaining my thought process/method, but there is no way I passed the technical phone screening but failed this one with the same set of answers. Other than this, the whole onsite experience is pleasant and I do feel the passion people working at Linkedin to make this product better its goal.
