10+ Quant LegalTech Interview Questions and Answers

DB query to find duplicates in a table, keeping first duplicate in answer.

• Use GROUP BY clause to group the records by the column(s) that may have duplicates

• Use HAVING clause to filter out groups with only one record

• Use MIN or MAX function to select the first record in each group

• Example: SELECT MIN(id), name, COUNT(*) FROM table GROUP BY name HAVING COUNT(*) > 1

Code to map Employee Object from List to Hashmap using Stream API functions.

• Create a List of Employee objects

• Use stream() method to convert List to Stream

• Use collect() method to convert Stream to HashMap

• Use Collectors.toMap() method to create HashMap

• Pass key and value mapping functions to toMap() method

The question is about finding the total number of handshakes in a meeting of 10 people.

• Each person shakes hands with 9 others.

• Total handshakes = 10 x 9 / 2 = 45.

Program to swap value of two variables without using a third variable.

• Use arithmetic operations to swap values

• Add both variables and store the sum in one variable

• Subtract the value of one variable from the sum and store it in the other variable

• Subtract the value of the other variable from the sum and store it in the first variable

Program to print prime numbers

• Start with a loop from 2 to n (number to check)

• For each number, check if it is divisible by any number from 2 to its square root

• If not divisible, it is a prime number and print it

A do-while loop is a control flow statement that executes a block of code at least once before checking the condition.

• The do-while loop is similar to the while loop, but the condition is checked at the end of the loop.

• The loop will always execute at least once, even if the condition is false.

• Syntax: do { // code block } while (condition);

• Example: do { x++; } while (x < 10);

Designing a new product involves several steps from ideation to production.

• Identify the need or problem the product will solve

• Conduct market research to determine demand and competition

• Brainstorm and develop concepts

• Create detailed designs and prototypes

• Test and refine the product

• Finalize design and prepare for production

• Launch and market the product

React is a JavaScript library for building user interfaces. Virtual DOM is a lightweight copy of the Real DOM, used for efficient updates.

• React is a popular JavaScript library for building user interfaces.

• Virtual DOM is a lightweight copy of the Real DOM, used for efficient updates.

• When changes are made in React, the Virtual DOM is updated first, then compared to the Real DOM to minimize actual DOM manipulation.

Ductile materials exhibit plastic deformation under tensile loading, with stress and strain being proportional until the yield point.

• Ductile materials can undergo significant plastic deformation before failure

• Stress and strain are proportional until the yield point

• After the yield point, the material experiences strain hardening

• Ultimate tensile strength is the maximum stress a material can withstand before failure

• Elongation at break is the amount of strain a material can under...read more

Pipe flows, stress distribution, divergence, and vortex flow are all related to fluid mechanics.

• Pipe flows refer to the movement of fluids through pipes or channels.

• Stress distribution refers to the way stress is distributed throughout a fluid.

• Divergence is the measure of how much a fluid is spreading out or becoming more diffuse.

• Vortex flow is a type of fluid flow where the fluid rotates around a central axis.

• These concepts are important in designing components that involve ...read more

The basic procedure to start drilling involves selecting the drilling location, preparing the drilling rig, and drilling the hole.

• Select the drilling location based on geological surveys and exploration data

• Prepare the drilling rig by assembling the necessary equipment and ensuring safety measures are in place

• Drill the hole using the appropriate drilling technique and monitoring progress regularly

• Extract and analyze rock samples to determine the composition and potential for ...read more

Embedded s/m refers to software that is integrated into hardware devices to perform specific functions.

• Embedded s/m is designed to perform specific tasks and is often used in devices such as smartphones, cars, and medical equipment.

• It is different from traditional software as it is tightly integrated with the hardware and cannot be easily removed or replaced.

• Examples of embedded s/m include firmware in a printer, operating system in a smartwatch, and control software in a dro...read more

Selection sort is a simple sorting algorithm that repeatedly selects the minimum element from an unsorted portion of the array and swaps it with the first unsorted element.

• Iterate through the array to find the smallest element and swap it with the first element.

• Repeat the process for the remaining unsorted portion of the array.

• Time complexity of O(n^2) makes it inefficient for large datasets.

An array is a data structure that stores a collection of elements of the same type in a contiguous memory location.

• Arrays have a fixed size determined at the time of declaration.

• Elements in an array are accessed using an index starting from 0.

• Example: string[] names = {"Alice", "Bob", "Charlie"};
