Confidence interview questions

I had the initial interview, which is very similar to first phone call interviews. Then I had an interview with one team member. Basic questions but the issue was that I was moved on to the next stage but they didn’t email me when they said they would, I had to email them. The third interview was with two other team members and I had to create a presentation on a software and sell it to them. They cut me off in the middle and went to basic interview questions. Then I was asked to do a follow up to this interview with more open ended interview questions. Again I had to reach out but they then informed me (two days after they said they would make the decision) that I didn’t get the job and they went with another candidate. But then I looked on LinkedIn and they put the job that was originally closed back up. It almost felt like a fake interview just to get poor saps to create presentations for them.

Got a simple take a home test which I completed in around an hour. The feedback (negative) whas the following: 1) Did not use typescript "enough" --> even though the ts-code-coverage was above 90% 2) Should've splitted the code in multiple files instead of having all in /pages/index.tsx --> whole file was 147 lines so no need to split it I only did the first step of the interview process and I am giving feedback on what I saw. Worst interview process so far for me.
