After taking two hours of interview they said they don’t have any job right now.Totally a Bad company who doesn’t have any value of candidates time.

I had Bitwise as a vendor for a year. I worked with Bitiwise overseas. They made my job easier due to our turnover at the company I was with. If you need a company that will keep your information up to date and meet deadlines, this is a good vendor to do business with.
