Revolut FinCrime Analyst interview questions

There were 3 rounds overall - assessment, HR screening call, TL round. All of these rounds were easy enough if you know your things. Was interviewed and passed all these rounds and receieved an offer letter mentioning CTC, Manager name and joining date. They also asked for my address. Signed and accepted the offer . But that was it. BOOM! They were gone suddenly! No contact, no revert of my followup emails - nothing - just ghosted me! Extremely unprofessional and trust me they don't value people or skills. Would never consider this company again.
