Gallagher Processing Associate interview questions

The selection process included assessment, HR round and op.round with manager. I had cleared all these rounds and the manager said he would tell the decision in 2 days. I waited for 1 week and I contacted the one who referred me and got the news that I was not been selected, the reason they gave was very funny, as they had rejected me for not responding. The most funny part here is that they are the ones who didn't responded to my call or mails. Such a cheap play from the hr and the manager to reject someone. Thank you for wasting my time. God bless you.
