How long have you been working in IT in total?

This question is usually asked to assess the candidate's experience. The answer should specify the exact number of years and months of work in IT, and if relevant, highlight experience specifically with Golang. For example:

I have been working in IT for about 4 years, of which 2 years are actively involved in Golang development.

If the experience is less, it is honest to indicate this, emphasizing the desire to develop.
