Basically the title. I have been working in the sales domain for more than 5 years and for the last couple of years, I absolutely hate it due to stress and lack of interest. I have been learning python inconsistently for the last 1 year but now I have shifted my gears and learning statistics and ways to implement it on the real world problems through Python. Internal transfer is almost impossible as it is a pure sales organisation which outsource equipment from China and sell it here.
I am a little bit concerned about my efforts and time which I am dedicating for the learning as I have gone through various articles and similar LinkedIn profiles and found one point of commonality i.e. Almost everyone had undergone a course based certification from Learning Sites such as Upgrad, Simplilearn etc. this questions my process of learning and making me worried about my decision to go on a self learning path. I don't have any Godfather in companies or good friends through whom I can at least apply for a refer. All I can do is to apply directly over the website. Would like to know your opinion?
