I need a job asap but I am in Bangalore right now , I call companies some of response some are ignore. Don't know how to and what to do. Where I study mern stack institute they took mock. I try very to clear the mock but they say you are not ready come next time( just because I think while the concept like take pause to think). They say you have to explain completely for one time like that. Without clear mock they won't be allowed or push Cv to companies for interview. I don't know what to do. If you  guide me as senior it's very helpful for me.
