Slack interview questions

Wasn't a very great experience. Compared to other companies, Slack's process seemed very slow - 1.5wks between each round. 1. Phone screening with internal recruiter 2. Zoom interview - current CSM - background, work experience, etc. 3. Zoom interview - with hiring manager (Director, APAC) 4. Zoom interview - chronological round with Director APAC & Senior Manager USA - deep dive into each role of career history 5. Zoom interview - Presentation Unfortunately I didn't make it through to the 5th round and received an auto-email advising this. I replied to the email politely requesting to book a quick call to go over any feedback from my interviews and areas where I can improve. During the feedback call with internal recruiter, I asked a number of questions and was only given very generic responses, when I asked for further questions for clarity I was advised "I really can't disclose a lot of feedback in detail to be honest, we don't generally", which was quite surprising and disappointing.
