Ericsson Junior Data Scientist interview questions

Round 1 - HackerRank algorithm test Round 2 - HackerRank algorithm test Round 3 - Call with recruiter Round 4 - ML live coding test. Round 5 - Virtual onsite (not a local candidate, in person onsite was not offered) of 3, 1hr Skype Interviews: 2 technical ML/stats interviews, and 1 behavioral interview. I found this to be the most challenging round by far. After being offered the role, I was given 48 hours to respond, which was only extended to 72. I didn't appreciate this because the final round was over skype and I wanted to be able to visit the location before relocating.

This was my first data science interview. 1st screen 10 Qs - General ML questions 2nd screen Hackerrank : 70 minutes both ML multiple choice questions and Python programming multi-parts 3rd Interview -ML with Python using Scikit library 4th Interview have no idea didn't make that far. Overall it was fair questions about concepts, models and performance. Style of questions were thorough checking data science basics and sometimes tricky contrasting competing choices. I think perhaps lots of false negative result comes out of this type of testing, it fails many good Junior candidates. Those who pass the test perhaps have good knowledge, not sure evaluating more than that. I'm sure result of this test, is NOT reflection of my capability but it was great critic so I improve myself. You have to be really prepared, because test covers quite a bit of data science material and coding time was short for multi-sections better to be on top of coding. Overall I'm happy took the test, but not happy with outcome. Ericsson is looking for Data Science engineers know basics and will code a lot, I imagine it can be tough job.
