On the contrary, I expect most tech companies to not be profitable especially in ZIRP era, unless they're big and public for many years (or small boutiques). If one is looking to work only at profitable companies, the pool of employer shrinks significantly. You can almost kiss goodbye to the vast majority of VC funded companies. It's not as bad nowadays but in ZIRP times, it's not the norm for growing tech companies to be profitable.
