Since they gave me a really disgusting experience, I wanted to share an interview here for the first time. If you are going to interview with them, keep these things in mind. The technical interview was an interview of average difficulty. Afterwards, a case study was sent and I was asked to solve and send it within 5 days. It was a very wide case study in scope, I took 2 full holiday days and an evening to create a full solution and sent it. 4 days after sending it, they sent a positive return and sent another technical interview meeting to explain the case study in detail. At that stage, I explained the case study in detail, and as a matter of fact, 30 minutes after the meeting, they returned that they were positive and we agreed on a date for the manager meeting. The manager meeting was a meeting where I explained the reflection of the findings in the case study on business processes. One day after this meeting, they called and asked for my reference numbers, asked about my salary expectation and stated that they would come with an offer after the reference check. Afterwards, they did not make any return for 2 weeks, and when I asked if they would return, they said that they were dealing with an important job and that they would make an offer next week. Naturally, I was under the misconception that they were a big company and I stopped applying for a new job and continued to wait for the existing interview process. Please do not make this mistake, continue your applications no matter what this company says. The next week, another friend called from the same company and asked the same questions that they had asked 10 times before and said that they would come with an offer. Towards the end of that week, when I saw that they did not come with an offer again, I wrote a message to them to be clear and then they called me and said that the offer process was delayed because the manager went on a trip to America and they said that they would come next week. and 2 more weeks passed and they did not come with an offer again, they said that they would come with an offer for a total of 5 weeks and they just stalled.

technical interview was easy, perhaps because of their urgent need for a data scientist. main subjects were forecasting techniques and data preprocessing, cleaning and how to handle various kinds of problems in a dataset.
