Hi there Jake! I'm glad that you are showing improvements on your English skills. Keep it up! Here are your corrections. ^_^

We usually have an hour for lunch break. It starts at noon and ends at 1o'clock in the afternoon. I go out with my coworkers when it's lunch time because there is no cafeteria in our company. It makes me very uncomfortable. By that time, I am really hungry so I go to the restaurant as quickly as possible. I am specially associated with my coworker. I met him when I was preparing for my job interview. We made a study group for the job interview. He was so critical when we did the simulation interview. It was helpful to me. Fortunately, we passed the interview. We are working in the same building that's why we can have lunch together everyday. There is a restaurant that we always go to because of its cheap prices. But I'm not sure if it's delicious. We like to talk about our company because it is something we have in common. After eating quickly, we walk around the office building while having ice cream. He is doing lots of things these days. He is exhausted now. I want to give him energy. Anyway, I'm happy to have lunch with him.
