Dentsu Senior Programmatic Trader interview questions

One of the most horrible interview experiences ever. The HR person working for this was extremely uninformed and ghosted me for 4 months. When the hiring manager finally got in touch with me, the conversation was barely about the job profile but more about me selling my skills and convincing I could do the job. After 4 months of horrible experience,I still had to be keep messaging and emailing for a follow up. Truly one of the most horrible experiences ever. It was insulting to be in this situation and there was no respect. The hiring manager was the most unresponsive person, changed the timings of the task numerous times.
