Lowe's Home Improvement Senior Java Developer interview questions

Hr contact via the job portal site Scheduled the interview on Weekend I went to the first f2f it was good, After that HR told to leave for the day. After 45 minutes, she called me where are you, I told her at home she is saying can you come once again, what the hell they are doing I told no if possible schedule the next round via skype. After a few days, I got regret mail.
