Am i able to grab a job by studying these codes ??

Question

for example studying SQL

Answer 1

I think when people employ you they don't even look at ur digree sometimes. They only test is that what you can do and how good you are in solving problems.

Answer 2

so can i appear in interviews by studying the codes provided by solo learn

Answer 3

Solo learn gives you the basics of each language and shows employers you have the basic skills of that language. If you're planning to have a back end job for a website for example I would pair your knowledge of SQL with PHP or another server side language.
Each employer hires differently, but I would recommend building your own portfolio of where you have used this skill. Some employers require you have a degree so Solo Learn alone will not place you an interview.
As I mentioned above Solo Learn gives you the basics of each language, try to expand on these skills with projects of your own.
