Certain things take their own course. When you threw out those resumes', were you right to do so? Now the shoe is on your foot so to speak and you don't want your resume to be dismissed for the same reason you dismissed so many.
Get a job with the best chef and restaurant you can. Work hard. The chef may not like you. You may not like the restaurant. If you do a stage, you may have the job by the end of the day. Or you may not get the job at all. You shouldn't expect to get hired. You should hope to get hired.
Why six months? Stay as long as you continue to learn, whether that is three days or three years. Work in a hotel, a catering company, steakhouse, fish house, vegetarian, fine dining, fast food and run of the mill. Develop good work habits wherever you are.
You continue learning after school the same way you did in school.When you aren't working, study cookbooks, practice at home, learn canning and preserving, baking, visit a farm and orchard, a slaughterhouse, a packing plant.
Open a book, practice, learn from others. How much you learn is not as much about where you work as it is the effort you put in to learning, which you can do all the time no matter where you work.
You don't burn bridges by showing respect for everyone. When you decide to work for someone, do your best, no matter what kind of place you find yourself in. When you decide to leave, give two weeks notice. Be aware of the reality that what you may end up experiencing and learning in any given place may not be what you expected to learn.
People skills, knife skills, organizational skills, cleanliness, communication and much more are all important. Some places will have more techniques to teach you than others. Some places will be more people experiences. Sometimes you learn how to do it right. Other times you learn what not to do. Sometimes people you work with will be horrible but most of the time, they are all just trying to get through the day, just like you.
Strive to be a good employee always. Learn what you can wherever you can. When you feel it's time to go, find a new job, give two weeks notice, move on. If you have done all you can to show respect for yourself and those around you, you won't burn any bridges.
