I got a few offers that were aborded midway for one reason or another, for example a few ones were cancelled after they realized I didn't had a EU citizenship (I made clear I was brazillian and lived in Brazil, but they assumed I had some kind of EU passport anyway... although legally I should have one, bureaucratic issues made me not have one) Also some companies asked me to do some puzzle style tests, that at the time I didn't pass.
