Internship report

Hallo everybody I have done an internship and hve to write an internship report. I was in rush to write this report, and did not pay much attention to the mistakes could someone read through it and give me some hints where should I change what. I appreciate your comments and corrections in advance. Thnak you for the time you shared for me.
Here is the part of the report:
The 6 month Internship had a great influence on me as a e business life and also the relations between people, showed me the direction through which I want to couintinue my education. I have always thought that internship is the same as school education where I should learn something connected with my education. But I realized that even photocopy making teach something to the person. I have learned not only about business life and also learned how to speak with different people, how to speak on the phone, attitude to the people how to act, being serious about my work. The task that I have completed during my internship were very interesting and egitici. They gave me self-confidence, responsibility. If I should sort out what I did and what I liked or I did not like during my internship, I start with Lieferantentag.

The lieferantentag was the greatest experience for me to take part in such an important organization and to organize it. I have learned lots of things during this task, as writing to the Suppliers, seeing how to organize a meeting, how the structure follows each other. As I said I did not learn only according to my education which is absolutely right these are the things which someone does not learn in books. The task for the zertifizierungsunterlagen has helped me most with my german as I had to speak with lots of people on the phone or mail writing, I feel my german has improved very good. This was one of the tasks where I had the high responsibility must say it was very interesting task that from this task I have learned about certifications, why are they important, most important responsibility gave me energy for doing my work perfect. The checklist project was also a very interesting and creative project. I had to push my thoughts how to design it and speak to the purchasers in order to know what they are interested in during an Lieferantengesprach. May be I did not take part directly in the Purchasing tasks, but the tasks that I have completed thought me lots of things about the purchasing department. This was the project which I handled it alone, and I can say had the highest responsibility. I am happy that I leave a project to purchasing department on which I have worked alone. Again as I said I have learned lots of things about business, about Bosch about purchasing not directly taking part but doing projects according to purchasing tasks
