Tip 1 : Make it a single-page resume(2 columns if necessary). Format it well. Use a small picture of yours near your name on top. Don't shy away from putting as many relevant links as you can, where people can see your work.
Tip 2 : Bullet point to the experience section. It can be chronological or can start from your best. Don't lie, definitely.

1. Nodes without siblings
Easy
10m average time
90% success
0/40
Asked in companies
You are given an arbitrary binary tree consisting of N nodes, your task is to find all the nodes of the tree that do not have a sibling.
A binary tree is a tree where every node has at most two child nodes.
Two nodes in a tree are called siblings if they are children of the same parent node i.e they have the same immediate ancestor node.
Note:
1. The root node is not considered as the node with no sibling.
2. If there are no such nodes, return -1.
For example, consider the following binary tree:
Here node 4 and 7 do not have any siblings.
Problem approach
Eliminated all parents which had 1 child. Recursion helped to keep track of the immediate (grand)parent node to attach the new node to. Balancing was the usual top-to-down approach.
2. Number of Islands
Easy
0/40
Asked in companies
You have been given a non-empty grid consisting of only 0s and 1s. You have to find the number of islands in the given grid.
An island is a group of 1s (representing land) connected horizontally, vertically or diagonally. You can assume that all four edges of the grid are surrounded by 0s (representing water).
