I did a first interview with HR and then a second one wirth two managers, I was assignes a task to do 2 days before the second interview. The task is difficult and you need time to do it. After spending days preparing the task I did the second interview and never heard from them again. Not even an email saying "thank you but we decided not to move forward". I reached out to them to ask for a feedback and they didn't reply. This is really not nice, doesn't seem like a serious company. Not recommended.
