Intertek interview questions

2 Hour Interview Breakdown 10:00 AM - Scheduled interview time. Reached at 9:45 am - Nobody at front desk. 10:15 AM - Met with a younger manager - typical discussion of past experiences, office visit etc. 10:40 AM - Manager asked me to sit/wait for 20 mins in the conference room - while the other two business development guys get back and we can all go for lunch. 11:15 AM - Manager comes to check on me and say the other guys will be here any minute. 12:00 Noon - Finally the two guys came and we went and had lunch. ( lunch was paid by them) 1:00 PM - Got back from lunch. Done with the interview. Pros - 1. Very laid back interview 2. Only good thing for me was "free trip" to Seattle. 3. Manager was very relaxed. Cons - 1. No follow ups - I followed up 3 times over email and still no email back. Had to finally call. Very unprofessional. 2. Do not trust verbal offers. 3. The whole process was nothing but a waste of time.

What kind of previous lab experience did I have?
