N-SIDE Optimization Software Engineer interview questions

The whole process has started with a phone meeting with a recruiter. It followed up with two other interviews. Both interviews went smoothly, and the interviews were friendly. The first one was with one expert from the same team to be familiar with the job requirements and the company environment. The second one contains three individual interviews with HR, two senior members from technical teams, and directors. The technical part includes questions regarding (pseudo)code, model, and analysis.
