Interview Questions and Answers

Implement array sorting without using the sort method

• Use a custom sorting algorithm like bubble sort, selection sort, or insertion sort

• Compare each element in the array and rearrange them based on the desired order

• Repeat the process until the array is sorted

SQL queries are used to fetch data from databases based on specific criteria.

• Use SELECT statement to fetch data from a table

• Use WHERE clause to specify the criteria for fetching data

• Use JOIN to fetch data from multiple tables

The bucket and water problem involves finding the minimum number of steps to measure a specific amount of water using two buckets of different sizes.

• Understand the capacities of the two buckets

• Determine the target amount of water to measure

• Use the operations of filling, emptying, and transferring water between buckets to reach the target amount

• Apply the concept of greatest common divisor (GCD) to find a solution

AI is not replacing humans, but rather augmenting and enhancing human capabilities.

• AI can automate repetitive tasks, allowing humans to focus on more complex and creative work

• AI can analyze large amounts of data quickly and accurately, providing valuable insights for decision-making

• AI can assist in healthcare by diagnosing diseases, predicting patient outcomes, and personalizing treatment plans

Document Understanding involves extracting data from unstructured documents using AI and ML techniques.

• Identify document type and layout

• Extract data using OCR and NLP techniques

• Validate and classify data

• Train machine learning models to improve accuracy

• Integrate with RPA workflows for automated processing

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order.

• Start by comparing the first two elements of the array and swapping them if necessary.

• Continue comparing adjacent elements and swapping them until the entire array is sorted.

• Repeat this process for each element in the array until no more swaps are needed.
