Importance of certification for the career and job search

by Alex 26. April 2009 16:07

A certificate does not mean to introduce you as an educated or experienced with some high prestige institute, company and organization. It depends upon the nature of your qualification. Suppose you are certified by Microsoft. It is great but it is obviously not enough to get even junior position at Redmond based giant. From my point of view a certificate doesn’t show your exceptional ability or ensure the selection authority that you are more competent than any one else. Certificate is the way to highlight your motivation or cover some basics in no crucial areas. [More]

Regular expressions in technical interviews

by Alex 9. April 2009 20:31

Working with regular expressions on the daily basis for the last five years I still use reference almost every time I need to write something somehow complicated. It is just unfair to expect candidate to know the answer right away on the white board. But again, it is something you just need to be prepared for; especially in this thought times then employers looking on big pool of candidates and can be picky. [More]

Binary Search Tree

by Alex 11. December 2008 13:37

A binary search tree (BST) is a tree in which every node's left sub-tree has a key less than the node's key, and every right sub-tree has a key greater than the node's key. The major advantage of binary search trees is that the related sorting algorithms and search algorithms, such as in-order traversal, can be very efficient. This data structure is perfect for advanced interview questions. [More]

Fibonacci numbers

Tree interview questions

by Alex 7. December 2008 09:46

As the simple case of a graph—a tree is a connected graph containing no cycles—the tree is very suited for an interview question, as it allows the creation of problems that are small and can be coded within less than 10-15 lines, but the solutions are not obvious and require good problem-solving abilities. Probably the most common questions are related to the binary tree. A binary tree is a special kind of tree, one in which all nodes have at most two children. For a given node in a binary tree, the first child is referred to as the left child, while the second child is referred to as the right child. [More]
