Had 3 formal interviews and 1 informal interview with the company. 2 formal interviews I had, the company did not even ask me my availability. They just sent me the invitation without any context. After the forth interview, I was selected and 6 weeks later they sent me an email stating that they've decided to select other candidate instead. The whole application process took 4 months and I've spent a lot of time and effort trying to get the position. Very disappointed by this company. If you have a chance to select other company instead of TT, please do so.
