Programming Languages

Hi Rohit,
As a programmer, you will be expected to be proficient in at least one language like Java or C+. However, you can always switch to other language that excites you intellectually keeping in mind that PHP, Python and Ruby are also very much exciting and useful in some situations of software development. The skills required as:
1. Problem solving.
2. Good command of data structures and algorithmic techniques (not necessarily know sophisticated stuff, but know how to use basic structures and techniques to most efficiently solve a huge array of problems).
3. Thorough coding abilities - translate your approach to code quickly. Debug and get it working for all possible corner cases. And yes, no pseudocode. Syntactic & semantic correctness is required. Comfort with a popular programming language (typically C/Java/Python) is most essential.
4. In case of a reasonably experienced candidate, system design skills (or) solving large scale data problems also become very relevant. If applying for a very specific team (such as mobile development or networking, for instance), of course, knowledge of that domain will be tested.
