In this article, we have compiled 19 basic questions to interview a programmer that will help you detect the technical and soft skills of the candidate and thus select the best professionals for the position.

This question is to know the passion that the programmer has in the area he works, whether he is a Backend, Mobile, or Full-Stack programmer, a programmer who has no passion for what he does in his area, is a programmer who is hardly going to deliver good results in a short time.

3. What did you like about your previous job and what was it you didn’t like?

This question should always be asked by default in an interview with a programmer. This way you know if the candidate knows the technologies required for the position. If the candidate knows most of the technologies and has used them in work projects, they are a good candidate for the position. Otherwise, you must evaluate if the candidate has the technical knowledge to fill the vacancy. Still, don’t immediately rule out a candidate because they don’t know one of the required technologies for the position. Finding candidates who meet 100% of the technical requirements of the vacancy is very difficult. The candidate can enter the company and learn those specific techniques that he does not know.
