Good overall, most of it was SQL . So if you are from software background raw sql can be tricky. You need to prepare well in that field. you also do the test on the platform before having an interview with the technical recruiter
Interview questions [1]
Question 1
1. most of the questions were data science related
I applied through a recruiter. I interviewed at Andela
Interview
I was contacted by a recruiter to particupate in an interview process for a Data Scientist position.
The interview went well and the recruiter said I had a strong experience for the role. However, they said they would send my profile to their client, and never got back to me.
I emailed then after a few weeks, but I was ghosted. I thought this was extremely disrespectful of my time, that they couldn't be bothered to even send me a negative response.
I took my time to prepare for the interview, and couldn't get back the smallest amount of respect.
