The first thing I noticed was the smell in the office. Very depressing environment, everyone seemed miserable. I thought it may have been only that day. I ended up going there 4 times and each time got the same feeling.
The interviewer was not a pleasant person. At my 4th visit they made me an offer for a different position (service technician). The offer was very low. I told them that I will think about it and get back to them. I wrote an email explaining what is market standard and what it should be, but they didn't even bother responding back. They didn't thank me for my time and that they can't meet my request. Very unprofessional!
