I once worked for a startup that did this - pretty much fired a lot of the competent engineers, or they quit. A lot of engineers complained about the ungodly hours many had to put in for unrealistic deadlines that were pushed down by sales. Supposedly the executives heard about the complaints that their best engineers were ready to walk out, and promised to change the way things were run - I got word recently that they were still continuing the same overpromising, which led to unsurprising unstable backend & frontend issues of various degrees. One product manager described it to me as setting everyone up for failure. I'm increasingly convinced that it is the sign of bad leadership, and people with no business being in management or an executive position.
