Behavioral Technical
The interview process involved one call with HR and another call with a People Manager and a Senior. The technical interview was quite good, the people were friendly, and overall it was okay. I recommend interviewing with them.

It was a really nice process. The interview questions with the manager were mainly about the tools used in the end-of-studies internship like power bi, the python programming language, and Machine Learning models.

Technical Coding Behavioral
I interviewed with Imperva Thales in Tel Aviv. It was a long process. First, there was a technical screening. Then, a home assignment that wasn't very interesting. After that, an online interview with 10 general data science questions. I also had an in-office interview. Finally, an HR interview and a meeting with the team. Sadly, the whole experience was really disappointing; they treated candidates disrespectfully. After all those stages, they ghosted me for a month and then sent a rejection by text, no phone call or anything.
