Questions

Career Blog FAQ

A short preview of common questions - the full guide answers 20 in detail.

How many jobs should I apply for every day?

There is no perfect daily number. For most candidates, applying to three to five carefully selected jobs is more effective than submitting dozens of generic applications.

Should I apply if I do not meet every job requirement?

Yes, you can apply if you meet most of the essential requirements. Job descriptions often describe an ideal candidate, and some listed skills may only be preferred.

How should I explain an employment gap?

Explain the gap honestly, briefly, and confidently. If you studied, built projects, completed certifications, freelanced, or improved your skills during that period, mention it.

How can I identify a job scam?

Be cautious if someone guarantees employment, conducts no meaningful interview, or asks you to pay a registration or processing fee. A legitimate employer should not require payment to provide an interview or offer letter.
