Advice from Human Resources at Berkshire Capital:
Students should make themselves very familiar with the company and the history of that particular company. There is an abundance of information located on the Web site of each company. Students should also follow instructions very carefully. If we request a writing sample, transcripts, SAT scores, cover letter and resume that’s what we expect from each student. All the required materials are what we use to make our decision on who we want to interview.
The main problem with over-researching is that it steals from other activities: namely, meeting people directly.
