The interview had two parts. The interview with a person and the second part was a technical interview. The technical was a case study. You are recorded, no notes are allowed, and no calculators are allowed.
It was very difficult. Need to prepare properly related to your CV. Also online assessment was really difficult as well. Prefer to practice well before you have an exam. Once you finished your exam, the result is saved for few years so need to be careful.
I applied through other source. I interviewed at Boston Consulting Group (Zimbabwe) in Jan 2021
Interview
honestly super easy since we spoke different languages, we didn't understand each other, we just shared a cig on call for 15 mins and played an online backgammon tournament against each other. Got the job cause I won at backgammon.
