Surreal. I went through five very easy tech screenings, all very similar, testing the same JavaScript knowledge repeatedly, except for one that tested React. They asked to redo one interview without providing any specific reason. I received positive feedback and proceeded to an offer. I was asked to provide a bunch of documents, had two more interviews with hiring managers, got in touch with people for references, negotiated the compensation package, and accepted it.

Then they disappeared. A week later, I learned through the recruiting agency that the CTO decided not to sign the offer because he didn’t like ‘something on the technical feedback’. Imagine what a nightmare of a top-down, micromanaging culture there must be if this person, with whom I had no interaction and wouldn't have worked directly, can completely disregard his employees' opinions and have so much say in the hiring process. By far the most unprofessional, opaque, and overall worst hiring experience I’ve participated in during my career.

Just basic modern ES6 questions.
