Just briefing you the jobscope and asking you which field you want to go to. Got an offer a week later but they rescinded the offer after two hours. When ask for a reasons, they only state they decided to go for another candidate. Imagine you already resign from your job after you were given an offer just to be told they "RETRACTED" their offer. If they can change people very fast, what more they can do once you actually join the company.

Email invitation for job interview position is totally different from the Job posting. Seems like they are just eager to fill up positions. There is no system in place for interviewing candidates
