LinkedIn Software Engineer interview questions

Contacted by a recruiter. 1 Phone interview with an engineer followed by on site. Standard interview process like any other company. The recruiter also provided useful pointers for the preparation.

I recently interviewed with LinkedIn for SWE Productivity Engineering team. I did around 200-225LC(easy, medium,hard). The interviewer asked me an array question and I solved it. Then he asked me a question related to BST(insert/Delete). I explained him the logic clearly and wrote the code. He was not able to understand the delete part(looks like he never did BST by himself or he didn’t even know the basic principle of BST deletion). I explained him multiple times and even with a diagram. Still he was not accepting the solution. After the interview I googled the question and I was 100% correct and my code was perfectly fine too. Then I saw his profile on LinkedIn. It seems like he was a salesforce.com developer for 6 years and recently converted to Sr.SWE at LinkedIn. Not sure why he asked me BST without knowing the basics of it. I felt bad for missing the opportunity!#engineering #software #swe Did anyone face this kind of situation before?
