All seemed very egotistical to me - far too focused on if I could memorise equations rather than the practical application & business impact of machine learning. I do not need to memorise mathematical equations to be good at my job. Not the place for me :) I felt very uncomfortable throughout the whole process, I'd personally prefer informal chats where interviewers put you at ease so you can really let your true self shine rather than egotistical interrogation. The recruiter also told me I didn't get the job at 10pm on a Friday... Not cool! And very off putting to know staff work that late.

Question 1
Explain how you calculate back propagation in neural networks
HR pre-screening. Although the overall process and the interviewer were excellent, they unfortunately did not support a work permit visa. Everything was transparent in terms of expected salaries, the following process, etc.
I applied online. The process took 2 weeks. I interviewed at Deliveroo (London, England) in Feb 2025
Interview
Initial HR interview. Then 1 hour technical screen where you are asked to explain 2 projects you've worked on and answer some systems questions. Didn't get past this stage, but next should be a take home task
I applied online. The process took 2 months. I interviewed at Deliveroo in Jan 2025
Interview
The whole interview process was efficient and well-organised. I was contacted by a recruiter just a few days after submitting my online application. Early on, I was given a clear overview of different interview stages (technical, business, and behavioural), and the preparation expectations were clearly communicated.
Feedback from each round was delivered quickly and in detail, which I truly appreciated. It's always great when a company provides genuine feedback, including both strengths and areas for improvement within a reasonable time.
From the recruiter to the interviewers and HR team I interacted with later on, the communication was consistently smooth, efficient, and respectful throughout. Overall, it was a great interview experience, and I also learned a lot about the company culture.
