The test was from 10 pm to 11:30 pm at night, Since we had to give the test from home so it was not an uncomfortable timing for me. The test was conducted on hackerrank. Personally I find Hackerrank a better test platform than others like Amcat or Mettle.

This interview was at 10 am in the morning and was taken by a SDE 3 of the company who had a very great background in Competitive Coding.
The interview started with me introducing myself. The interviewer then gave me a google doc which had 2 coding questions written . He asked me to go through the first question and explain the approach. After which he asked me to code the solution as well. Same procedure was followed for the second question. The most difficult part in using Google Doc to write code is that it doesn't has automatic indentation like the code editors, so I had to put much efforts in keeping my code readable.

The round was at 4 pm evening. This round was taken by one of the Vice President of the company, this made me anxious from the very beginning.
The interviewer was a knowledgeable man and had great knowledge in every field. He always demanded exact answers.

Interview Preparation Tips
Tip 1 : For company like codenation you need to be great in competitive programming as the online test is very difficult to crack
Tip 2 : Focus on leetcode during final months of preparation of interview
Tip 3 : Try to have at least 3 flagship projects in at least 2 different domains
Tip 1 : Keep the resume clean with good text to space ratio.
Tip 2 : Don't mention tech slacks that you have only a little knowledge about as it can backfire if the interviewer is good in that tech slack.

Interview Preparation Tips
Experience: A separate debugging (also on Hackerrank )round was conducted.
Round: Technical Interview
Experience: 2 rounds Technical interviews (1-2 hours each ,online on Skype and Hangouts )
General Tips: 1) Start practicing on codechef.com as early as possible (even first years). Go to the Practice Section -> Easy problems and start solving from bottom to top.
2) Participate in Codechef Long and short contests every month
3) Once you are good familiar with basic algorithms you can also solve problems on Hackerrank and Codeforces.
4) I do not prefer reading books. Best resource for learning algorithms is search on Google and see the top 3-4 links.Personal blogs and sites like leetcode and TopCoder tutorials are helpful.
5) Once you are comfortable with coding, you can refer to GeeksforGeeks and CareerCup in the last few weeks to practice company specific questions
6) Try to do at least one course every semester from a MOOC like edx.org , coursera.org .
