Parexel interview questions

I applied online, got an email and phone call a few minutes later asking for a telephone interview. I had this interview a few days later which went very well. I got moved to the next stage which was the writing test, I sent my test back 6 days later, called to confirm that they had received. The recruiter promised to get back to me shortly. After a week and no contact I called her and promise to call me the next day. two days after that I still didn't hear from them, so I call again and no answer, call a few more time and it was not answered. I decided to hide my number and immediately it was answered, she promised to call me back the next day and guess what she never did. I called a week later, she picked up the phone as I introduced myself, she hung up and would not pick it again when I rang back immediately. This is the most disgusting recruitment process I have been through, it was an absolute joke, Whoever wants to work for this company, God help you and for those who are working for them, I feel really sorry for you.
