Internal tools

What are the internal tools you can use at work? Just joined and there are a lot of homegrown tools, but kind of missing the usual Zoom and Slack, Jira, Trello, Notion, etc.. Just curious what productivity or comm tools or apps or what not you get to use where you're at. Kind of surprised not even on Microsoft teams/365. Are most places just making everyone use homegrown stuff, email, etc? TC: $180K, 20% target bonus, no RSUs, 7 years
