J'ai postulé via la recommandation d'un employé. J'ai passé un entretien chez UBS
Entretien
I got a message from a senior person who is in my LinkedIn regarding a data scientist role at UBS. I interviewed with him for the first round. Asked basic questions about my resume and whether I'd any experience building APIs which I had.
Next round was scheduled with a data scientist from the team. The person called late and was not professional at all. He grilled me on several points
NLP, CNN, LSTM, Word2vec etc

Question 1
What's stemming and lemmatization?

I answered most of the questions. It's been more than a month and they have not got back. What unprofessional people
I hasn't been invited to the interview after the initial screening, which was business reasoning questions and work style questions. It took me around 60 minutes to complete this test.

J'ai postulé en ligne. J'ai passé un entretien chez UBS (Londres, Angleterre) en oct. 2025
Entretien
Had 2 interviews with the team, then a case study, an interview with the global head, and another interview with HR. So 5 total rounds... The final call with HR was very positive, but they never mentioned an offer, although signs that there would be one. In the end the position was offered to an internal candidate, however I was never reached out to by HR... after 5 rounds and such positive feedback was really expecting the HR to at least be honest with me and tell me I did not get the position.

Question 1
With HR I was only asked about salary and visa status, both which were ok.
HR round. This section is the easiest, mostly here for screening and validation of the profile
Tech round with team. Most challenging section
Final round with panel. Didn't get to this point
