I dont think it would make you sharp. It would train you for ugly politics, back stabbing and general chaos. But it would not train you for good performance. You can actually hide incompetence very well in chaotic companies if you can talk well and take others credit. And competence without political clout gets punished (because it is easy).
Being sharp as in the positive performance terms requires sharp leadership and decision making. It means leadership that actually knows what is going on and that requires trust. That is not the same as rage layoff after you impulse bought company you dont want while trolling on social medias.
