UNOPS Product Lead interview questions

I applied online and received an email about being shortlisted. I was asked when I could complete a written test. I submitted my date and time. I received no reply to confirm it. Then, on/at the day and time, I followed the instructions. I wrote ststing that I was ready for the test. An hour later, I was sent the test (an hour late!). Thus I withdrew. Not a professional process at all and the HR didn't even seem apologetic about being non-responsive and late!
