I have no relation to Starfighter, but I was part of a similar startup almost a decade ago, and learned a few things that are likely similar to what they faced. We started with this dream of completely revolutionizing the way people hire in tech (with hopes of expanding to other fields). First of all, we learned that for 99% of companies they don't have a screening problem, but they have a sourcing problem. Our original company was along the lines of HackerRank / LeetCode / etc, and created due to the founder's experience as a manager at Amazon where he'd get 1000s of resumes that needed to be screened and the process was eating up too much dev resource. A product that solves this problem is appealing to companies that get 1000s of resumes per posting, but basically useless to most companies who get very few candidates, and even less appealing to recruiters who care much more about top of the funnel than the screening process. After that we pivoted to an event format. The idea being that we could attract 100s of applicants to do a challenge in realtime. This reduces cheating risk and allowed us to act as a means of sourcing candidates (instead of just a screening platform). The idea was 100s of candidates would enter and the companies we got to sign up would compete for the top applicants. It sorta worked. The platform was good, companies were interested, and we got some people placed. HOWEVER, the profile of people that will do a multi-hour open ended challenge for the chance to maybe get hired by some companies largely leans toward entry-level people. We had some experienced people that did it because they were bored or just curious, but generally seasoned engineers aren't going to waste their time, and forget about "passive job seekers" which is what all recruiters want most of all. Ultimately, the company ended due to a lot of personal issues between the founding team, but the product itself was good, and the market fit was decent, but far from perfect. I'm pretty sure if we would've kept it together we would've eventually became very similar to HackerRank just offering a platform where people can conduct the same crappy tech interviews we've been using forever.
