Steve Jobs was many things: technological genius, eccentric billionaire, master marketer, and notable jerk. Like most people, he was not all good, and certainly not all bad. He helped revolutionize the world of personal computers and mobile phones.
When we say Jobs was a little bit crazy, we don’t necessarily mean it’s a bad thing. Sometimes he was crazy smart, rather than just plain crazy.

Here are the dark sides of Steve Jobs

• He would harass people interviewing for work.

• He also nearly blew up his third grade teacher.

• Jobs often parked in spots reserved for the handicapped.

• He was a well-known egomaniac, Jobs was infamous for being difficult and demanding. In 1993, he held a spot on Fortune’s list of America’s Toughest Bosses.

• He Fired People With No Notice.
Jobs had a legendary temper. He was known for firing people over the slightest of errors, both at Apple and during his time at Pixar.

• He short-changed his best friend on a bonus.
When they made Breakout for Atari, Wozniak and Jobs were going to split the pay 50-50. Atari gave Jobs a $5,000 bonus. Jobs didn’t tell Woz about the bonus though, and paid him half of the original price of $750 while Jobs got $ 5375 for being the delivery boy.

• When his parents dropped him off at college, he never said goodbye. He recounted the moment later with uncharacteristic regret: “It’s one of the things in life I really feel ashamed about. I was not very sensitive, and I hurt their feelings. I shouldn’t have. They had done so much to make sure I could go there.

• He never put license plates on his silver Mercedes (despite driving it constantly). How did he do it? California has a rule that a car owner has six months to put plates on a new car. Jobs just changed cars (to the identical model) every six months, allowing him to drive without plates.

• He wanted nothing to do with his daughter for a long time

For years, Jobs refused to acknowledge the existence of his daughter, Lisa. He even claimed he was unable to produce and would not take a paternity test. It was heartbreaking for Lisa and her mother, as they struggled financially. Despite this, Jobs named one of his early Apple computers after her, the Lisa I and Lisa II. Eventually, he seemed to grow up and accept responsibility.
However, he ultimately made the situation right, he started paying child support and reimbursed the state of California for years of back child support. He ended up connecting with Lisa and she became a member of his family.
But it doesn’t change the fact that it’s a very sad story.

He was quoted as saying : Raising kids is hard. And when you have a kid you feel like this enormous energy and creativity you have for the world is going to get misdirected into a little baby

• He Didn’t Listen To Doctors.
Jobs was diagnosed with pancreatic cancer in 2003. The good news is that is was a rare type that was actually very treatable and the prognosis was that he could probably recover from it. Instead he bizarrely ignored the doctor’s advice for the better part of a year, trying to cure the cancer himself with a mixture of eating healthy and natural medicine. He eventually agreed to the surgery, but it was too late. The cancer would continue to cause numerous health problems for Jobs until he passed away in 2011.

Comments from his employees

Employee 1 – I’ve worked with many billionaires in my career, and Jobs was the biggest asshole I ever met.
He would destroy people just for the fun of it. He would make it personal.
Even on the original Mac team, there was a small number that Steve treated with respect, and the rest he treated like shit.
It’s also true that at NeXT and then his return to Apple, Steve grew up and learned to treat people better. Steve v2, he learned a lot of lessons and was much improved.

Employee 2 – Steve Jobs was a man on a mission, and if you and your incompetence got in the way of his mission, he would belittle you until you either disappeared, changed your ways (adhered to his wishes), or blew up back at him. If you were right, he would respect your truth and change his ways. If you were wrong, he would never speak to you again.
He was also somebody who loved and valued those closest to him dearly. He loved the Macintosh team, he loved his family and he loved his computers. He was apparently fiercely loyal to those who mattered most to him.
Things just seemed to be very binary to Steve. He either loved you and was fiercely loyal to you, or you weren’t much of anything to him. There was no grey area for acquaintances, no room for mediocre friends or products. In particular, there was no time.
Steve Jobs has always stated that he feels that time is his most valuable resource.
He always felt that he would die young, and he didn’t want to waste his time for a second on mediocre things.
That’s the root of Steve’s behaviour.
