For the past couple of years, government and societies have been trying to make “Geek” cool again. Presidents and prime ministers are recommending that computer programming be part of schools’ curriculum. Politics aside, becoming a competent programmer today is more challenging than ever. Just being an introvert genius no longer suffices.
Companies and organizations are looking for people with cognitive skills to add to their technical abilities. It is difficult to put a number on this as it is very company-dependent, but the 70/30 rule could be applied here. That means that people should possess roughly 70% technical skills and 30% soft (cognitive) skills. A “hardcore” developer hardly moves into management if he/she lacks the soft skills required. I have managed many teams across multiple verticals and developed some job descriptions and career progression paths along the way that are in use in some of the largest companies in the world. Let’s try to sum up a few aspects of what seems to be the pattern when companies are recruiting or promoting.
Well, this is a no-brainer; your technical skills will get you the interview. When recruiting a Java developer, companies are looking for several factors.
An understanding of the

It is good to know
http://en.wikipedia.org/wiki/Code_monkeyhow to write code, but knowing the reasoning behind your code and/or your chosen algorithm will make you stand out from the crowd.
Mainstream Programming Tools
Today, the fact is that you cannot be a jack of all trades (master of none). You have to pick which tool you are going to master. This is sometimes dictated by the environment you are working in, but let’s say it is a good bet to go with the following:
http://maven.apache.org/Maven or Gradle.
SCM: Git (not GitHub. Big difference).
IDE: Netbeans or
http://www.eclipse.org/Eclipse – not just for writing code, but also code refactoring and debugging from the IDE. I came across plenty of developers who did not how to debug from their favorite IDEs.
Mainstream Programming Frameworks

It's great that you have a deep knowledge of the Java programming language and various tools, but your employer/clients will also be assessing you on the following aspects.
Communication is key to everything we do. We have to interact with the environment around us, whether it is in our private or professional lives. This is not just the ability to put words together, but how to communicate problems that we are facing, or proposing solutions to those problems. A great communicator knows how to express herself in front of various groups; remember that something that makes clear sense to you might not be the same from someone else's perspective.
Developers are problem solvers, philosophers, and thinkers. Don’t be one of those programmers who only writes code and doesn't get involved in the discussion about how to solve problems. Don't be the programmer who says, "Tell me what to create and I’ll create it. Don’t ask me if it is the best way to do it."
All developers work as part of a team, whether it's with paired programming or a large project. You need to contribute to the team's objectives and goals. Help mentor junior members along the way or assist struggling members in overcoming their hurdles. Don’t have an “I’m just here to do my job and then go home” attitude. Be part of the team. You don’t have to make silly jokes to become “team clown” or always go out on team events but be a team player.
This is a very important skill to have; the ability to acquire new skills on your own time. Do not always wait for the company to provide you with training. You need to go out there and learn new technologies and advance in your field. From front-end development to architecture patterns, there is always something new happening. Read blogs and articles and try to join local meet-up groups. What you learn can open up new vertices for your career.
This blog post was not supposed to be this long, but the aim was to tailor it to be useful for aspiring developers — or even veterans.
