I applied through college or university.

I attended the first and second round yesterday. The first two rounds were handled by GUVI. I had to create an account in GUVI. They will give the access code to attend the rounds.

• First Round: 10 multiple choice questions. Pointers. Predicting output and choosing the right code given the output. Very easy round.
• Second round: After finishing the first round, you can take a break, leave, or continue with the second round. No elimination after the first round. Both rounds are considered together. There were three questions: Easy, Medium, and Hard. All three were different sub-questions revolving around the same basic concept.

Those who cleared the second round had a telephone interview two days later. People who were selected in that round were called for a hackathon in Bangalore.

Note: In the coding round, you are allowed to run or submit your code only ten times per problem. So keep track of that count. Don't run your code unnecessarily. Code complexity is also very important. Take care of that too.

GUVI people are very nice people. You can ask them whatever questions you want to ask. They won't be able to help you with anything regarding the questions, though. If you don't understand the question, no one will help you.

The first question's input was 23, which is the number of nodes, and an edge array of 23 values. The edge array's value indicates the node connected to the "i" node. For example, the first value E[0] is 4, which means the node with value 0 is connected directly to the node with value 4. The other input was 9 and 2 to find the node with the shortest distance from 9 and 2. The output was the node with the shortest distance where 9 and 2 can meet. The second question was to count the number of edges in the graph. One more question was to find the exit points in the graph for a node. If the next node is -1, it implies an exit.
