Haven't ranted in a while so here it goes.

Head of product took me (senior dev) to a high value client workshop/demo session and over the course of two days found the reason behind why the dev team has been pushed to the limit as of late and sales/product team has been making promises to clients without checking with dev leaders on reasonable delivery dates on massive new features.

I tried my best to manage expectations by differing talking about delivery dates by saying "lets discuss that with the team" rather than giving out dates right now. But as soon as the meeting ends he sends an email to the client confirming delivery dates on features that we have done no research on or even specialize in!

Please tell me this is not how well established businesses work or is that the new reality of things. In either case I wanna find a new job :/
