Can a native speaker of English check structure and grammar of the sentences, thanks?

Today I went to a company for an interview under the scorching sun.I applied for the post as an secretary.I felt a bit nervous because I didn't have any working experience on this aspect.The Deputy General Manger gave me some material about secretarial working,and let me take them home for a systematic understanding in order to prepare for the second-round interview.I hope to get this job very much,so I will try my best.Good luck to me!
