(2 Questions)
- Q1. Opps, Java concepts
- Q2. Why is string immutable in java?
- Ans.
String is immutable in Java to ensure security, thread safety, and optimization.
Immutable strings are thread-safe as they cannot be modified concurrently by multiple threads.
String pooling allows Java to optimize memory usage by reusing common string literals.
Immutable strings prevent security vulnerabilities like SQL injection attacks.

Sort an array of 0s, 1s, and 2s in linear time complexity.
Use three pointers to keep track of the positions of 0s, 1s, and 2s.
Traverse the array and swap elements to their respective positions.
Time complexity: O(n), Space complexity: O(1).
- Q2. Spiral order traversal of BST.
- Ans.
Spiral order traversal of BST
Use two stacks to traverse the tree in a spiral order
Push the root node into the first stack
While the first stack is not empty, pop a node and print its value
Push its left and right children into the second stack
Once the first stack is empty, swap the stacks and repeat the process
Continue until both stacks are empty

Interview Questionnaire
5 Questions
- Q1. Basic java core questions and project questions
- Q2. Hashmap vs hashset
- Ans.
Hashmap is a key-value pair data structure while Hashset is a set of unique values.
Hashmap allows duplicate values but not duplicate keys.
Hashset does not allow duplicate values.
Hashmap is implemented using a combination of hash table and linked list.
Hashset is implemented using only a hash table.
Example of Hashmap: {1:'one', 2:'two', 3:'three'}
Example of Hashset: {'apple', 'banana', 'orange'}
- Q3. Arraylist vs hashmap
- Ans.
ArrayList is a resizable array while HashMap is a key-value pair data structure.
ArrayList is ordered and allows duplicates while HashMap is unordered and does not allow duplicate keys.
ArrayList is accessed by index while HashMap is accessed by key.
ArrayList is suitable for storing and accessing elements sequentially while HashMap is suitable for fast lookup of values by key.
Example: ArrayList - List
names = new ArrayLi...
- Q4. Abstract class vs interface
- Ans.
Abstract class is a class that cannot be instantiated, while an interface is a contract that a class must implement.
Abstract classes can have implemented methods, while interfaces cannot
A class can implement multiple interfaces, but can only inherit from one abstract class
Interfaces are used for achieving multiple inheritance in Java
Abstract classes are used for creating a base class for other classes to inherit from

FICO interview questions for designations
I was interviewed before Jun 2016.
Interview Preparation Tips
Experience: There were 2 objective written tests, 1st one had one section of mathematics questions (CAT like) and one section of Data Structure, C/C++ questions, 2nd one had only mathematics questions but they were tougher than those in the 1st test
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

- Q2. What are ways to speed up SQL queries? List them in increasing order of complexity?
- Ans.
Ways to speed up SQL queries in increasing order of complexity
Use indexes on columns frequently used in WHERE clauses
Optimize queries by avoiding unnecessary joins and subqueries
Use stored procedures to reduce network traffic and improve performance
Consider denormalizing tables for frequently accessed data
Use query optimization techniques like query caching and query hints
- Q3. Is Redis single-threaded or multi-threaded?
- Ans.
Redis is single-threaded.
Redis is single-threaded, meaning it can only execute one command at a time.
This design choice allows Redis to be extremely fast and efficient for certain use cases.
However, it also means that Redis may not be the best choice for highly concurrent workloads.
- Q4. What sort of data types can be used as keys in Python?
- Ans.
Data types that can be used as keys in Python include strings, integers, floats, tuples, and custom objects.
Strings are commonly used as keys in Python dictionaries.
Integers and floats can also be used as keys.
Tuples can be used as keys if they only contain immutable elements.
Custom objects can be used as keys if they are hashable.
Examples: {'name': 'John'}, {1: 'apple'}, {(1, 2): 'tuple'}
- Q5. What types of indexing exist in SQL?
- Ans.
Types of indexing in SQL include clustered, non-clustered, unique, and composite indexes.
Clustered index physically reorders the table based on the index key
Non-clustered index creates a separate structure for the index
Unique index ensures that all values in the index column are unique
Composite index uses multiple columns for indexing
