LinkedIn Software Engineer In Test interview questions

Got a recruiter message from LinkedIn on LinkedIn. First had technical phone screen, later was called for onsite where i met multiple software engineers. Experience at LinkedIn was kind of weird since i thought few employees who interviewed me had some attitude problems, which made me loose my interest in the company while interviewing. I was interviewing for Software engineer in test position and my experience lies in UI automation and in code analysis, i was asked OS concepts, multi threading, thread pool etc. which was not needed totally. When i asked the interviewers how much multi-threading you guys use at LinkedIn for automation, they said 'No we don't use multi-threading.' It was a great set back that i was being checked for the skills, that i don't have experience with or in job description or thats not used in the company itself! Overall, i was not that happy with the interview experience and even if i would have got the offer, i would have declined the offer.
