 they told me a creepy excuse and after that, she stopped replying to my email. How can they do this to anyone?
 At least they can give genuine feedback. A person who came for an interview with a lot of hope especially if you asked to come second time for face to face . 
 I will not recommend anyone for this firm and also I know that people are in need of change or job but please confirm all things prior.
 They are not doing things in a professional way.
