This service is a waste of time. They first sent you this test on HackerRank that is very easy if you've been doing a lot of interview problems. After that, they have you talk to this INCREDIBLY busy guy who interviews everyone who applies. You can only set up an interview once every 1-2 weeks. He had me talk 3 times with him. One as the initial conversation, the second to clear up any interview questions I may have, then the "mock" interview. It took over a month and then he finally said that someone else will contact for me jobs and it is not a guarantee that they will have any jobs for me. Why have me go through this month long process for nothing? My advice, hire more people to interview... people can't be waiting for nothing for over a month.

First filled out an online application followed by a brief coding exercise consisting of two problems for which I was given 90 minutes. They were relatively simple. Next was invited to an interview which was held via video chat where I was asked about myself, my interests, and experience. This was followed by a 'whiteboard' coding exercise which was also pretty simple and was told I passed. Interviewer was very friendly and helpful giving me advice for future interviews. Very positive experience.
