Morgan Stanley Interview Questions, Process, and Tips

To check palindrome and anagram of a string with O(n), use a hash table to store character frequencies.

• Create a hash table to store the frequency of each character in the string.

• For palindrome, check that no more than one character has an odd frequency.

• For anagram, compare the hash tables of the two strings.

• If the hash tables are equal, the strings are anagrams.

• If the hash tables differ by only one character, the strin...read more

Optimized solutions and core principles applied in OOPS

• Encapsulation, Inheritance, Polymorphism, Abstraction are core principles of OOPS

• Optimized solutions can be achieved through efficient algorithms and data structures

• Design patterns like Singleton, Factory, Observer can also be used for optimized solutions

To debug Out of Memory Error, analyze memory usage and garbage collection algorithm of JVM.

• Analyze heap dump to identify memory leaks

• Check if JVM is running out of heap space

• Analyze garbage collection logs to identify any issues

• Tune JVM parameters to optimize memory usage

• Consider using a profiler to identify memory-intensive code

• Check for any large objects or arrays that may be causing the issue

Automated parking lot design with efficient space utilization and user-friendly interface.

• Use sensors to detect available parking spots

• Implement a central computer system to manage parking allocation

• Incorporate user-friendly interface for easy navigation and payment

• Maximize space utilization with multi-level parking and compact car storage

• Ensure safety measures are in place for pedestrians and vehicles

Design an auto-suggestion feature for a search engine.

• Implement a search algorithm that suggests relevant keywords based on user input.

• Use machine learning to improve the accuracy of suggestions over time.

• Allow users to easily select and add suggested keywords to their search query.
