I recently attended interviews at LinkedIn, attlasian and my experience was very bad. First round is online exam and I answered all the questions. Attlasian rejected even having 100% right with all test cases. No response from LinkedIn. They told I can use any language to solve and I chose bash. I think they didn't like me using bash. The guy who interviewed me at LinkedIn is system administrator with sre title. Funny thing is he said he doesn't do programming. Companies are just misusing these titles. They need software engineering who can do system administration. The types who run apt-get on Centos :p
