Very bad experience. Slack HR does not care about giving you a call and feedback. Even if you perform well, they would just go silent and simply say, "We would not proceed for this position."

They ask pretty simple questions in technical coding. They provide Slack.db PostgreSQL, which has a few tables, and they ask to write a query. Then, you run the same query programmatically through any language. Typical queries.

Slack might be good in other places, but in India, they are like any other average startup. Not a good vibe. HR is pathetic.

A simple SQL query on the user and team tables.
