J.P. Morgan Senior Applications Developer interview questions

It's really disappointing that such a big company does the interview process like this. It was a diversity drive and they named it WOW (wider opportunity for women) There were 3 rounds first one coding test 2 face to face First round being coding test I assumed this is going to be for development position and I am pretty much into Java development I have finished all the rounds pretty well and expected the positive result At the end of 3rd round they said that I am not apt for the position😳 It was very clear that they are doing these drives not seriously. I wasted my complete day for nothing, the least they could do is explain why I was not apt. Because my profile and JD matches. And if it is not apt they should be knowing at the initial rounds not after final round. Sorry for the long review but I just wanted this to take out of my head. And I have also heard similar experiences with this company from my friends Really disappointing,if it reaches concerned person hope they take the required action.i still respect the organisation but please train your staff to adhere to your values and rules.
