Basically, they use their applicants to do free work for them without the promise of a job.
The interview process began very normally: a 1-on-1 interview with a hiring director and a series of interviews with higher-ups in the office. Then came the sample project. Basically, the sample project is doing free work for them without even the promise of a job. They give you a prompt (which I believe is an actual project they are receiving money for) and you try to recruit REAL people to speak with them about it. You use all of your personal accounts and they give you no payment, not to mention a guaranteed job.
Luckily, I came to my wits after only working on the project for a few hours and told them that I would no longer do it. Please, if you value yourself beyond doing free work for a company that doesn't even employ you, do not continue in their process. I couldn't imagine the anger I would feel if I worked for hours on a real project for them, unpaid, and then didn't even get the job.
For any Ridgetop Employee reading this: please change this about your hiring process. Everyone I spoke to about this was weirded out about it, and many reached out to me to stop the process because I was "better than that." There are other ways to gauge success from a candidate than by exploiting them for free labor because you have the upper hand.
