Criteo Senior Data Analyst interview questions

Interview process is easy. However, the recruiter is way too unprofessional. I have been interviewing with Criteo for the last month and a half. First call was with the hiring manager, second was an excel based case study where they let you to choose the tool as per your convenience. Then, the recruiter tells me the feedback was nice from the hiring manager and ghosts me for 3 weeks. I reached out to the recruiter for an update regarding the next steps, he says I am no longer considered for the position as the team thinks now I have not used python in the case study. Then after many requests the recruiter schedule's another call with the hiring manager and tells me to go through the entire process again., The recruiter didn't gave me an update after the interview, I had to reach out to him again and then he tells me we will be considering you for an entry level position based on your experience. FYI: I am a Master's graduate with a Degree in IT and Analytics from the US with5+ years of work experience. Overall, the recruiter is way too unprofessional and would not recommend any of my fellow data professionals to go through the same. It is really disheartening as I had prepared alot for the interviews.

Completely unprofessional experience interviewing at this company. Their timeline didn’t make any sense and it always felt like you were just waiting for someone to Get around making a decision. It shouldn’t be something that goes on for months🙄
