I applied online. I interviewed at Isomorphic Labs (London, England) in Oct 2025
Interview
- Initial screen
- Take-home assignment
- Leetcode-style coding round
- ML debugging round (live coding in a notebook environment)
- ML scenario interview
- Cultural interview
These last 4 rounds are grouped together as a virtual on-site round
Interview questions [1]
Question 1
- Coding round is a standard (medium-hard) leetcode question
- Be prepared to answer questions about "classical ML" (e.g. traditional NLP methods, cross-validation, classifiers, etc.)
Rubbish company has no respect for candidates. Avoid! Negative experience throughout the entire interview stages, extremely lengthy process, and at the end they ghosted you, do not waste your life interviewing with them.
Thanks for sharing this. We make every effort to reply to all candidates to let them know the outcome, no matter which stage they reach - be it the initial application review or progressing through the different interview stages. Sometimes the emails we send can end up in spam so it's worth looking to see is this happened. If somehow no email was received at all please get in touch with us by emailing the Talent team so that we can investigate this further. Thanks again.
Did not even get a reply (neither yes nor no!) after finishing the entire interview loop!
Quite lengthy process:
- Take home ML assignments
- Recruiter screen
- Hiring manager chat
- Coding
- ML debugging
- ML theory
- Culture fit
Thank you for sharing your experience and bringing this to our attention. We're looking into what happened, as we see it as important to update everyone on the status of their application. Meanwhile, if you can contact us - either by emailing the recruiter you were dealing with or by emailing talent-acquisition@isomorphiclabs.com - we will be happy to discuss this further.
