Interview Preparation Tips

Round: CODING ROUND
Experience: In the coding round there were 3 questions to be solved in about 3 hrs.

Round: HR Interview
Experience: Expect the usual crazy questions like "Why LinkedIn?" and if you are already placed, be ready to give a proper justification for "Why LinkedIn and not XYZ?" so on. Be cool, you need not be accurate. Be well prepared with your resume and expect questions from them.
Tips: For the interview, just be confident and have a good resume ready with you.

Round: Other Interview
Experience: Coding Interview:
Simple coding questions. Make sure you first explain the logic to them and then you may be asked to write the code for it on the board using any language of your choice. Syntax is not a big deal, but don't make any logical errors. They are very friendly and may suggest certain solutions of their own. Make sure you can grasp them quickly. Find faults in your own code before they find it. Always try to give the best optimal solution. In case you are unable to do so then suggest possible improvements.

Round: Other Interview
Experience: Design Interview:
Some people may find this round a bit uneasy. But this round tests how good you are at designing solutions to problems. Most of the candidates were asked to build an online gaming system. And then they keep adding extra constraints and ideas and see if you can integrate them to your design. Database knowledge may be tested. They may also ask questions pertaining to you projects listed in your resume.

General Tips: An updated LinkedIn account with decent connections. ;)
Skill Tips: Be very strong with your coding ability. Whenever you code, do follow some standard procedures and make the code look simple and structured. Whenever you solve a coding question make sure you answer it completely for all the test cases. Partial results will only indicate that there is something wrong with the logic. Try to solve a complete question rather than multiple questions with partial results.
