I am a graduate student and am planning to apply for an internship for Summer 2015. After looking at the websites of various companies offering internships, the most common file-formats acceptable for resumes seem to be .doc, .pdf and .txt files.
Now I am most used to typesetting all my documents in Latex. However, when I was about to create a resume in Latex, a friend told me to write my resume in .doc format, and then have it exported to .pdf, .txt etc depending on what the companies list as their preffered file format.
He said that since companies are usually deluged by resumes, software programs parse the resumes for keywords a company is interested in. say GPU computing or machine learning. Only then does a human go through all the resumes which have filtered through. Hence, my resume should preferably be submitted in a .doc or .txt format whose text can be easily parsed by a computer, unlike PDF.
Is this statement true? What are the pros and cons of submitting my resume in these two formats?
