So I graduated last semester with a degree in business, it it wasn't until my senior year that I got into the world of data and coding. First it was R code and then SQL. My buddy told me about a job he got for a company in coding and he has very little coding experience but very high level math skills. I applied and during the phone interview they told me that coding answers need some work but are still interested in hiring me if I can get my skill up a bit. I bought a Java Text book and the online question package. I am also looking at Ruby through some apps on my phone because I see that it's a lot easier and should teach me the basic blocks quicker. To shorten this long story, I am running off to Greece for three months with my wife to visit her family and I want to take this break to really bunker down and work on my coding skills. Any recommendations on what to focus on (the company has their own coding program but they want people who already understand let OOP concepts) if things don't work out with this company I would like to have a backup goal. What is the demand in right now? What should I be focusing on?
