So horrible experience to the interviewers. Three out of four interviewers did not treated me seriously. The highest level interviewer was even so rude to say "You don't know this? No offense, but I'm curious that didn't you learn this in college? My kids even learned this at school!" It's not no offense. It's very mean! I wouldn't want to work under such a manager no matter I was hired or not! Beside, the questions she asked were not for every entry level, which I applied for and I didn't have much experience just shown in my resume. I have no idea why they asked the questions so different with those posted here.
There was another interviewer, who was the last to interview me, he was in a meeting at that time but no one told me. I asked another interviewer to contact him for me and he didn't contact me until the last 10 min of our interview. It was not himself, but he asked another colleague to interview me and the colleague did know nothing about what he should ask. At the end, this interviewer finished the last interview in 10 min.
Were they serious to the interview? At least they were not to me. But they didn't cost anything for interviewing me, so they could waste my two and half hours. Terrible company, can be seen from how they treating the candidates.
Of course, they didn't show their attitude about offering me or not, even I contacted the HR in 10 days after the interview. The HR said he was waiting for the response from the department, and then I did not hear them again until now. This is the final round interview, please!
