      Candidatura

      Ho presentato la mia candidatura tramite un selezionatore. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso Deliveroo (Londra, Inghilterra) nel mese di ott 2022

      Colloquio

      It was meant to be in three stages but I didnt pass the first stage as the interviewer felt he didnt get enough signal during the interview. The first stage used to be just project discussion but python and engineering questions have now been added which was not communicated to me prior to the interview. I mentioned that to the interviewer who apologised but still evaluates my responses.

      The interview process is different from the typical processes where the judgement is based on solving a hard problem. Here the assessments are based on practical knowledge and skills. There were 5 rounds: screening, assessment, ML theory, ML system design, and behavioural.

      Domanda 1

      Screening: Questions about current projects, python, neural networks.
      Rispondi alla domanda

      Domanda 2

      Colloquio

      It was one of the best interview experience for me Recruiter was friendly and actually rooting for your success. Interviewers were knowledgeable, very professional and interesting to connect with. But the best thing about the interview was timely and detailed feedbacks between the interviews and at the end too There were total of 5 rounds (excluding recruiter screening) - Tech Screening [ELIMINATION ROUND] : It was chat about my past projects, why i took an approach for a project and some quick technical questions around that - Assignment Round [ELIMINATION ROUND]: Got a regression task to be completed in 24 - 48 hours Got feedback on first 2 rounds ONSITE ML theory round : This was the round i got the no in. I have mentioned few of the questions asked in Q/A section. ML practical round: It was more like a case study round where i was asked how would i help CRM team in detecting fraudulent tickets raised by customers. Behavioural and Business Acumen Round: Again i have mentioned major theme of questions in Q/A section and as the name goes this round revolves around behavioural aspects and its just my hypothesis but this round also plays a role in determining which role level you will be end up getting offer for. I haven't mentioned much about rounds here as Deliveroo has done a brilliant job in mentioned about it on their website.

      Thank you so much for taking the time to write such an extensive review. I'm sorry it didn't go further this time, but hopefully we will have an opportunity to cross paths in the future.
