10 weeks of interviews for a "Communication" rejection I spent 2.5 months in Revolut’s hiring process for an Upper Middle ML Engineer role, going through 7 rounds of interviews. All technical stages were passed successfully, with no concerns raised at any point. The issue: after 10 weeks, I was rejected due to “communication issues.” If it takes a company that long to evaluate how a candidate communicates, the problem is not the candidate - it’s the hiring process. This should be identified in the first 1-2 stages, not at the very end. Throughout the process, it increasingly felt like the expectations were closer to a Product Manager than an ML Engineer. This lack of clarity creates unnecessary friction and wasted effort on both sides. After investing significant time, I received no actionable feedback. Follow-up messages were ignored. This shows a lack of respect for candidates’ time and effort.

6 stages: leetcode, ml, probability, maths; ML system design, HR, final with hiring manager. Leetcode is easy/medium. Probability is standard coin tossing stuff, AB testing, knowing the basics of probability etc.

Was contacted on LinkedIn by their in house recruiter where it was apparent that I had 1 year and 8 months of experience in the field for a role that wanted 2 years. Replied fairly quickly and they took over a week to get back where they invited me to a video interview. Waited for 10 mins for the scheduled interview before emailing to check all was okay, no message about being late, continued waiting until 10 mins before the end of the slot when they turned up. Seemed all good they told me they were sending a coding test over and then was told that I didn’t have the 2 years experience by their team (fairly apparent given they had seen my LinkedIn and CV well before this stage) so they wouldn’t be pursuing this any further. Overall a very disappointing experience and very unprofessional.
