I went through three technical interviews: the first was a coding question, the second involved coding plus a C++ technical question, and the third was another coding question. The interviews were fair and focused on problem-solving and technical skills, with coding questions being easy to medium difficulty. A fourth round was set up, but the interviewer didn't show. HR said they'd reschedule, but then there was no contact. I was ghosted, and it felt poorly managed with a lack of communication and professionalism.
