After the technical interview I have got an immediate feedback and was assured that the company wanted to work with me, BUT here is only one small detail - a security check.
So, I spent 2 months to these checks. There was a questionnaire, including data about my family (!), polygraph (pseudoscience!). The process was slow and nothing happened unless I asked.
After two months of this process they just told me that I have passed the previous stage of the security check, but "sorry, we just decided to close this position with our internal employee". When I have asked why they answered "it's our decision". Very useful!
Don't recommend this company to anyone.
