This is a super tough, but incredibly valuable thread. Thank you all for the raw feedback.

I need to be clear: I 100% agree with the core sentiment here. As a candidate, the hiring process is often broken, dehumanising, and feels like a one-way street. Many of you are right when saying a tool like this could be abused.

I'm not trying to automate the human part of hiring. I'm trying to fix the part that's already broken.

The real-world alternative at most companies isn't a friendly 1-hour chat with a senior engineer for every single applicant, that just doesn’t scale.

The alternative is:

1. A harsh, biased CV filter that rejects 95% of applicants in a couple of seconds.

2. A 4-hour take-home exercise that massively wastes your time and is genuinely pointless because anyone can vibe code it.

3. An algorithm test from a platform like HackerRank for which the majority of engineers have to prep many hours.

I built Niju to be less painful than those. It's a 20-minute, practical, "think-aloud" test. The AI's only job is to summarise the data so a human can review it faster, making it more likely they'll widen the funnel and give more people a shot beyond just their CV.

My goal isn't to replace engineers but to stop wasting their time on a broken process, so they can have better, human interviews with the top 20% of candidates.

It's a massive challenge, and this thread, as well as most of the others, show the raw nerve I've hit.
