Recruiter reached out, they emailed my references from the start. Only after my references checked out, they sent me an OA which I felt was fairly difficult, I got 3/4 questions and then they rejected me.
Interview questions [1]
Question 1
An OA with an industry style problem that gets progressively harder each time
Coding screen in 4 parts. First 2 parts were easy enough. Progressively more difficult and you can't advance to next stage until all test cases pass. Unfortunately didn't make it to the final stage due to a single test case. Score was higher than they said was required but I didn't progress.

Question 1
They asked for references, didn't get to interview stage.
I interviewed at Anthropic (London, England) in Sept 2025
Interview
Got an OA to do after a month. The OA was a code signal industrial coding framework. Did not pass the OA. The next steps in the email said.
Based on a holistic assessment of your application, CodeSignal, and written references, we will advance candidates on a rolling basis through three additional rounds. These are:
A 55-minute coding challenge over Google Meet using only core Python functionality (no ML or libraries needed)
A 55-minute coding challenge over Google Meet on prompting and engineering with LLMs in Colab
A 15-minute research brainstorming round with an Anthropic researcher over Google Meet

Question 1
Codsignal OA sent after a month of application. It had a weird format of 4-levels it was level by level coding for classes and oops in python. Given from a non-cs background I found it challenging. The email had a google form to be sent to your profs for recommendation letters. They won't contact for you.
