The interview process was great until the end, when they ghosted me after the final round. It was very strange, they told me they'd be in touch shortly but after a month of follow up no response at all. I saw the job posting was unlisted.
It's sad to see a company do this to its interviewees. The least they could do is to follow up with a rejection or an explanation for the delay.
I will say, the interview process until the ghosting was very transparent and very egalitarian. They gave approximately 75% of the interview questions ahead of time, and made sure to follow up after each interview.
