The CEO is an ineffective leader. He is rude, arrogant, and lack of respect to people work for him. Some of the older comments say the CEO screams to people - still true today.
Don't expect to learn or get inspired from the CEO. No constructive feedback ever. No words of appreciation at all. You may still grow in this company by learning from others, but not from Jack. Good luck if you have to report to him.
If you can find a position with someone shielding you from Jack, you would probably enjoy all the Pros above. But if not, try to have at least one 1 on 1 conversation with him in one of your interviews, and think hard if you can deal with him.
