Positive ExperienceGot Offer
Process
I applied online. The process took four weeks.
- An introductory phone call giving me a chance to ask questions and testing my technical knowledge and ability to say when I don't know the answer and then reason about what an answer might be.
- A follow-up interview asking for more technical knowledge, at the end of this a short coding challenge was given.
- There was then another call to go through the coding challenge.
- Finally, I had an on-site interview with two parts, one to reason about the design of a large distributed system and another to dive deep into various technical areas.
Questions
To explain the threading mechanisms in Python, this question had the goal of getting me to say I didn't know and then reason about possibilities.

Seriously exciting
Backend Engineer • Current Employee
London, England
January 30, 2020
Pros: I've had the best time of my career at Monzo. The technical level, specially amongst the more senior engineers is much higher than anywhere else I worked at before, to the point that some of them are industry leaders in their domain.
This combined with the high level of trust and autonomy given to engineers has allowed me to greatly develop personally and professionally. I wouldn't want to be anywhere else.
Cons: The usual problems with a fast growing company. Things seem to change before you can get used to the previous state and some people cope better than others.
