I applied online. The process took 2 months. I interviewed at ING in July 2015
Interview
I applied in May, got first contacted in July by HR and then had a technical interview with 2 data scientists.
The HR sent me a list of basic questions I had to answer by mail.
The technical interview was on Skype and 60 minutes long. They sent me a mail with the outline of the interview a few days before.
I got contacted the following day by one of the two interviewers. He told me they didn't want to continue with me and asked me if I wanted some feedback, which I accepted. Basically he told me what they liked and what could (should?) have been better. The feedback was fair and honest.
Overall the process was nice, I have nothing to complain about. You have to be patient though, as you can be waiting for a few weeks between two steps.
Interview questions [1]
Question 1
The first mail the HR sent me included these questions:
1) What is the most impressive achievement you have realised? (e.g., medallist in math/informatics olympiad, winning a Kaggle competition, authoring a widely used Python or R-package, PhD at Ivy-league university, winning a Piano competition, ...)
2) Which technical/scientific discovery/method that you have developed are you most proud of in either supervised learning or unsupervised learning (or both)?
3)What salary are you looking for?
4) Which languages do you speak?
5) Did you deliver any contributions to open-source machine learning libraries? Or are there any contributions you really liked?
6) What’s your best example when you described something technical……to a non technical?
The technical interview consisted of:
- my background,
- interpersonal skills,
- a real life case study.
Firstly it was a test. Couple of months later I've had a call with manager and later with direct product owner. It has taken 2-3 weeks for final answer and enrollment.

Question 1
First question was about data and how you process it in models in a typical way.
I applied online. The process took 4 weeks. I interviewed at ING (Bucharest, Bucuresti)
Interview
The interview process was smooth and well-structured, with technical questions that gradually increased in difficulty. This approach made the discussion feel comfortable, engaging, and gave me the chance to showcase my skills step by step.
The process had several rounds. It comprised an initial online tech assessment (some multiple choice questions and a sql and python exercise), HR chat, personality interview, case study and one final chat.
The case study was a take-home assignment to be discussed in an hour interview.
Overall they were professional and kind.
