Pros
People are gracious, hard working and diligent. They are glad to help you if you ask. There is trust in you to solve hard and challenging problems. If you can prove your ability, you can even choose what to work on and what not to. No need to talk, talk, talk. Just get the work done and you are good and solid. You have to learn a lot to survive here no matter what.
Cons
Get the work done here is not easy. Can you work long hours? Think about 70 hours per week. Think about doing this one year. Think really hard whether you can. Think about running back to your computer 10 mins before your movie Saturday night. Think about doing this over and over again. Think about working on Friday night, public holidays, your anniversary night or your birthday night. Think about the opportunity cost. You can spend 40 hours on the work and the other 30 hours on anything else meaningful to you in another company. If you are gonna spend the 30 hours on TV or video games, maybe this place is a better choice to spend your time. If not, think about your choice. Finally, think about what the culture would be after I mentioned all of this. Everyone is nice, but you could still feel frustrated, helpless and desperate. Because there is a guy who stays with you no matter when you are at the office. His name is Company Culture, who is the really bad guy. He can force you to do tons of things you do not want to. He can make you cry at 2am when you are the only one at office. But you cannot argue with him neither fight him. No one can fix him in the whole company. Maybe you think you are tough. Think twice.
