Strings in Java are immutable to enhance performance, security, and thread safety.
1. Performance: Immutable strings allow for string pooling, reducing memory usage. Example: String s1 = "Hello"; String s2 = "Hello"; both refer to the same object.
2. Security: Immutable strings prevent unauthorized modifications. Example: Passwords can be stored as strings without risk of alteration.
3. Thread Safety: Multiple thread...

Round: Technical Interview
Experience: I was asked some question on my resume, about the projects I had done, academics etc. Then he asked me to suggest a data structure I would use for a certain problem. He kept on increasing the complexity of the problem and asked me the suitable data structure at each step. The second interviewer asked me to propose a model for credit card security. He too kept on increasing the complexity level of the problem. The third interviewer asked me to redo some of the questions I did wrong or couldn

Interview Preparation Tips
Experience: The test was conducted online. All the questions were of medium standard and easy to crack if we have patience for thinking.
English comprehension level is slightly below the standard of CAT. Those who have the habit of reading English news paper can easily crack the test.
Data analysis questions were also of medium standard. Those who have knowledge about graphs, bar & pie charts can easily crack the exam.
Tips: Practice Aptitude questions from R S Agarwaal book and CAT material.
Round: Technical Interview
Experience: Over all interview experience is cool. Interviewers never grilled on anything. In many cases they have helped me to arrive at answers.
Tips: Read C++ and Oops concepts from E Balaguruswamy text book.
For Data structures and algorithms read 'Data structures' by Yeshwant kanethkar.
Minimum knowledge about all the courses of your department will be an added advantage. This will help you to depict you are sincere in your studies and don't have any personal constraints in learning a new thing.
General Tips: Just be confident and believe in yourself. You will get through.
Skills: Programming skill in C++
College Name: NIT Warangal
Motivation: No special motivation. It is a rapidly growing company offering good package.

Interview Preparation Tips
Experience: Though technical questions were not that difficult but the quant section was way too hard and almost impossible to solve completely in given time limit.
Tips: It’s better if you attempt less questions (in quant) but do them right (I attempted less than 40% quant and still got through).
Round: Technical Interview
Experience: Next they would have 2-3 technical rounds where they cover most of the areas of CS. Some of the areas where they concentrated more would be Algorithms, OOPS Concepts and Logical Puzzles.
Tips: Brush up important concepts from various areas such as Operating System, OOPS, Software Engineering. Be ready for some really challenging questions in Algorithms. Also they do ask quite a few logical puzzles so it’s important you practice a lot of them online before the interview.
General Tips: D E Shaw selects very few candidates + comes in starting weeks of placement season, so competition is immense. Multiple companies come on same day, so it becomes a little tedious. Surely I wasn't the better candidate that day.
Skill Tips: D E Shaw focuses more on your ability to solve logical problems, so make sure you are in best state of your mind and speak while solving any problem because what they are looking for is not the right answer (well of course they are) but also how are you approaching the problem.
Skills: Operating System, OOPS, Algorithms, CS, logical puzzles, Quant
