Interviews were not too challenging, possibly because it's a QA position. They focused on basic debugging questions that a QA would deal with daily, along with simple C programs and algorithms questions.

No special preparation is required if you know how to write simple C programs like atoi and perform string manipulation.

Do your homework on compensation, as they won't negotiate at a later time. Entry-level QA positions may have some perks missing, so be ready to quote a higher base salary.
