I applied online, got the reply after half a month with a online test on codibility. The test was really easy, and I only took 30 minutes to finish all of them. There are three questions with total time of 90-120 minutes. And after 3 days, I got the invitation to the assessment day, according to the email, "This is the first stage of a two stage process. If you are flying internationally for this day then please let us know in advance. We cannot guarantee an all-in-one process however if we have the resources for it then we will try our best." I am scheduled to take the assessment day this friday, but just got email they have got enough people. Very angry at them!! I bought pants and formal bags for it, and they are the only company which requires dress coding (even not for google!!)
