I applied via Approached by Company and was interviewed in Aug 2024. There was 1 interview round.

Round 1 - Technical 

(5 Questions)

  • Q1. Discuss the project you are most proud of
  • Ans. 

    Developed a mobile app for tracking personal fitness goals

    • Used React Native to create a cross-platform app

    • Implemented features such as goal setting, progress tracking, and workout logging

    • Integrated with wearable devices like Fitbit for automatic data syncing

  • Answered by AI
  • 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

  • Answered by AI
  • 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.

  • Answered by AI
  • 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'}

  • Answered by AI
  • 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
