PHP Interview Questions

Interviews for IT jobs including PHP jobs often include challenges far beyond the usual questions regarding career aspirations.

IT interviews often consist of brainteasers, riddles and practical questions designed to measure your logic, reasoning, creative thinking, and problem-solving skills. The objective for the interviewer is not only to assess your technical knowledge, but also your communication skills and suitability (culturally) for the company.
