Slack Senior Software Engineer interview questions

I interviewed last week at Slack, It's just a waste of time. After my on-site interview, they got back to me and said they held hiring for this position because of the market situation, Really? how they didn't know last week about that?

Phone interview with a recruiter to discuss the role and your experiences. The recruiter has a list of technical questions they will ask you and you'll have an opportunity to ask questions at the end. Video interviews with multiple engineers involving live coding, behavioral questions and system design. Overall, the experience wasn't bad but I did end up leaving with a negative impression of the company. They will keep you updated and respond like you're the only one in the world but as soon as they don't need you, you become strangers and will be ignored. It might have just been the recruiter but the recruiter does represent the company.
