Nilex interview questions

I studied the company website & 3 people doing the interview from LinkedIn. I dressed professionally , drove an hour to the office & interviewed well. Less than a day later they sent me a rejection letter. I followed up by phone...the receptionist happily forwarded me to the manager. He yelled he was in a meeting and slammed the phone down!! How rude!! And he never called back to apologize. Terrible guy! Glad I didn't get the job here if that is how they mistreat people.
