The interview process was structured in two parts, the first one being a behavioural interview and the second one a case study. The case study was about modeling a mixed-integer optimization program related to scheduling orders together with the interviewer.

took an online assessment and got the phone interview within a month. Then I had a 1-hour phone interview, which is a case study. No coding question. After that, they did not get back to me until they finished with the hiring process and sent me a standard no-reply email.
