the hiring process is not well organized. i got a call from HR recruiter for first phone interview it was just typical HR screening about why you applied for this job, what you know about this company and where your availability to start and most important is salary expectation. she will ask if able to negotiate it to minimum underpay if possible unprofessional screening from such big company. Few days later I've received a call to go for face to face technical interview with a manager and TL. attended to interview on the following week. they will start with behavioral question for almost 30 mins and some technical questions and will last with some technical lab on debian to prove the ability how to solve some issue related to apache and mysql. the manager was silent for the whole interview he does not know what is going on he did not ask even a question another guy who conducting the interview he is really no idea what is linux he just trying to prove that by what given to him unexpected unskills both of them of doing interview at that low level for such a big company in the world.
