I wasn't given a chance to showcase my skills at all, we just had a 10min intro call with the recruiter who basically asked about my latest role and then asked about some logistical questions. 2days later I got a rejection email.

Monzo lay out their hiring process clearly in their comms with applicants and back it up with some great blog posts that genuinely do set you up to succeed. The process is friendly, flexible and grounded in real-world challenges, so there was no need to cram binary-tree backflips just to pass interviews for a role that didn't need them.
