Revolut Financial Crime - Head interview questions

Handled Unprofessionally. Waste of Effort and Time. I was approached the 1st time to apply for a Head of Compliance & MLRO role, after I passed the initial phone interview I was told I would be receiving a home task. The home task never arrived, I sent an email after not hearing anything and was told the position is "now closed". Weeks passed, I was approached on LinkedIn (again) for the second time by their internal recruiter to apply for another role at Revolut. After I passed the initial phone interview, I was sent a home task which takes a week to complete (this time it arrived), it involved a root cause analysis and coding knowledge. One of the nights I stayed up till 3AM as I have a full time job and time is a constraint. Submitted the results within deadline, there was a delay in marking the assignment, which they apologised for initially. Finally I get the results confirming that I passed the assessment and the feed back was positive all in all, a 3rd stage interview was arranged. Interview time was at first moved and the interviewer changed, then on the day of the interview, I got an email telling me the position is "now closed". After all the effort spent allocating time for interviews, spending a week analysing large data and putting together a presentation of the results, I feel they could have easily avoided wasting my time by improving their internal hiring processes. Since this is a regulatory position, I hope their approach to regulation and relationship with the regulator is more considerate and not as chaotic, otherwise it won´t end well. Luckily I already have a position, so this was no issue for me. However, if you are out of work, I would say effort and time invested pursuing a role at Revolut could be better spent focusing on a more professional and reliable organisation.
