ZestIoT Technologies Python Software Developer Interview Questions and Answers

The entire L1 discussion (with Bar Raiser AI) was divided into three phases -
1. Online coding test - A question related to Object Oriented Programming was given (two classes).
2. Verbal Questions regarding Python Multithreading limitations, decorators, testing (unit testing and integration testing) were asked for.
3. This third phase is unique to Turing wherein we are given a conversation between a user and a AI bot regarding a Python problem's solution. The AI itself suggests two solutions for the problem, and we are asked to judge which amongst the two responses is better and why.

Given a problem on OOPS concept.

Moderate level coding test is conducted

Advanced level coding is given to solve

Q1. Write a program to where a robber should be able to rob max amount of money from 9 houses, alarm will ring if 2 consecutive houses are robbed
Ans. 
Program to maximize money from robbing 9 houses without triggering alarm for consecutive robberies
• Create a list of money in each house

• Use dynamic programming to keep track of maximum money robbed without triggering alarm

• Consider robbing or skipping each house based on previous robberies

• Example: houses = [10, 20, 15, 25, 10, 30, 50, 5, 40]

Q2. What is a recursive function
Ans. 
A recursive function is a function that calls itself within its definition.
• A recursive function must have a base case to prevent infinite recursion.

• Recursion can be used to solve problems that can be broken down into smaller, similar subproblems.

• Example: Factorial calculation using recursion: def factorial(n): return 1 if n == 0 else n * factorial(n-1)
