What other skills are required to become a developer?

With the pervasiveness of agile development methodologies, programmers must show that they can integrate into mixed-skilled development teams, said Ed Szofer, chief executive officer and president at SenecaGlobal. "To be a productive member of these types of teams, programmers must be able to communicate clearly, report progress accurately, raise issues promptly, and generally be a good team player," Szofer said. "In today's ultra-competitive environment, a programmer's soft-skills are now almost as important as the hard skills."

Problem-solving skills are also highly sought after for developers, said Mark Wilcox, vice president of business development at ICSynergy.

"What I look for is, 'How does a programmer think about solving a problem?' And then I look for action they are taking in learning how to improve their skills," Wilcox said. "I don't care as much if they are an expert in a specific language because any competent programmer can learn a new language in a week. But if they don't have good problem-solving skills and are not constantly trying to improve, then they will end up hurting your project."

Especially for junior developer positions, "[employers] really don't care about what you think you know," said Todd Millecam, CEO and principal consultant of SWYM Systems. "Focus on how quickly you can learn and how willing you are to learn."
