면접 전에 means before the interview.

• 면접 = interview
• 전 = before
• -에 marks the time point

So 면접 전에 literally means at the time before the interview.

A useful pattern is:

• Noun + 전에 = before the noun
  
  • 식사 전에 = before the meal
  • 수업 전에 = before class

If you use a verb, the pattern changes:

• Verb stem + 기 전에 = before doing something
  
  • 가기 전에 = before going
  • 먹기 전에 = before eating

The particle -를 / -을 marks the direct object of the verb.

Here, the direct object is 이력서 (resume), because it is the thing being printed:

• 이력서를 인쇄하다 = to print a resume

Since 이력서 ends in a vowel, it takes -를, not -을:

• vowel-ending noun + 를
• consonant-ending noun + 을

Examples:

• 커피를 마셔요 = I drink coffee
• 책을 읽어요 = I read a book
