At first it seemed promising, with quick responses from the HR and I managed to arrive at the second stage of the technical interview within a week since first contact with the company. HOWEVER the tech interview was conducted by a third-party company which brought forward problems that could be brought in the first 3h-long automated test and had 20 minutes to solve each problem in a live coding environment. After dedicating roughly 5h of labor to the company between interviews, mcq questions, developing software, machine learning pipelines, SQL, data structures with live coding... they sent an e-mail thanking for taking part on the process with no effort of the company to give feedback whatsoever. I do not recommend wasting time with a company that has no intention to value concretely, sending a decent feedback, the time you dedicate to solve their problems.
