Extremely negative experience. The entire process took about one month and included an HR interview, a technical interview, a test assignment, and a conversation with the CEO.
The earlier stages moved relatively quickly until it came to the CEO call. He first rescheduled the call a couple of hours before it was supposed to start, and then postponed it again. When the call finally happened, he joined from a coffee shop where he was barely audible. Then we switched to Zoom, and during the presentation of my test assignment he kept interrupting and never actually let me finish.
The most striking moment came at the end, when he said they had already hired a designer for the role. Seeing my confusion, he tried to justify it by mentioning a possible part-time opportunity in the future. Later, I learned from HR that they had not hired anyone, which means the CEO simply lied during the interview.
After that, I received a rejection without any explanation. You can draw your own conclusions about such a process. Overall, fairly typical C-level behavior.
