How do I determine my level of programming (beginner, Junior/Intermediate, Senior/Advanced)

Question

Someone asked me this question and I couldn't answer it perfectly.
How can this be measured?
Is it by number of projects done or number of years I have been learning a programming language?

Answer 1

Since you are using SoloLearn, it is sure that you are atleast a beginner.
Now, try to solve problems given in-
www.hackerrank.com
www.hackerearth.com

If you can solve those problems easily, you are an intermediate level,

then try- www.codechef.com

If you are able to solve problem of those, easily,
you are a senior/advance programmer.

Answer 2

It is your overall knowledge and experience. Average standards:
Junior - good knowledge of core language, basic knowledge of frameworks and additional tools (Git, SVN, unit testing software, etc.), This is a starting point for earning money from programming. (excluding freelance where you often can meet programmers even below this level),
Middle - excellent knowledge of core language, good knowledge of frameworks, experience at team working,
Senior - excellent knowledge of language and main frameworks, good overall experience and competency at IT industry. This experience level is roughly equal to about 5-7 years of working as a programmer on various business or popular open-source projects..
