Merck Biochemical Engineer interview questions

Applied online. Took close to a month to get my initial phone interview. Phone interview was about 15mins. I was about why do you like the position and brief discussion of resume. I was told if i qualified i would hear from them by end of two weeks. It took exactly two week to get my site interview. Site interview started at 9am and continued to 4pm. I met one on one with each of 8 managers. Each interview me for an hour or 30mins. Mostly situational question, "was there a time when...?" "how did you you react...?" "given another chance will you do the same thing you did?" "what will you do when you notice a faulty equipment?" etc. I was again told I would be notified by two weeks if i was chosen. It is a week and a half now. i have had two calls from HR asking for some clarification of my documents. still waiting to end of week to hear the outcome.
