Phone interview, followed by another phone interview, which was exactly the same, just with different questions. Then, nothing.

Yes, that's right. On the first interview, I solved the given problem. Then they scheduled another phone interview. It went well; however, I found the interviewers to be really unprofessional and kind of rude. The whole process felt like I was talking to machines reading a script – really, no human factor in the whole process. At this point, I knew I did not want to work for this company.

I wrote the recruiter an email expressing my disappointment. He replied, saying he would take a look and give me feedback.

I never heard back. I accepted another offer, but out of curiosity, and for the purpose of this review, I decided to call the recruiter 10 days later.

The guy told me he had left LinkedIn for another opportunity and that he also really disliked how things were done there. We ended up laughing about it together and congratulating each other on our new gigs outside of LinkedIn!!

My recommendation is the following: I would never work for a company that treats applicants like an assembly line. Know that they are lucky you decided to apply, and they should know that too. They should make you feel comfortable on the phone and motivate you to solve the problem, not just throw you a question and sit back, reading a script.
