Implemented the functionality and shared the code. took about a week for them to come back. But my test was rejected with absolute no feed back. I pushed for the feedback through my agent but heard nothing. I even paid in Hack hands for 3 experts to point out what was wrong. But all of them mentioned the service was implemented as specified in the requirement I was given. (These experts charge £2 - £5 per minute) All i wanted to know was the mistake I've made so I learn from it disappointed with the company as this was second time. (first time I had cleared 2 rounds. I was even confirmed for 3rd round. But after 2 weeks, they came back saying they closed the position)
