Don't waste your time!! Started with a phone 30min interview, then called for an on site. Passed the on site, but suddenly got a homework task (it was not planed) and had to come again to their office to show my solution. Passed the second on site, then they called me to meet the executive members and the CEO itself, passed it as well and been told that I should get an offer... It never came, and every week to 3 weeks they gave me some excuse and promised I gonna get it soon. Eventually after about 3 months they finally told me that I should not waste my time because they don't really know when they will be ready.
