Question 1
Round 1: Technical + HR Interview
The interview started with some basic questions about SDLC (Software Development Life Cycle) and general concepts.
After that, I was given three coding questions to solve:
Swap three numbers without using a third variable
Check if a number is prime
Generate a Fibonacci series
Since my department is AI & ML, they also asked a few machine learning basics, including:
What is Machine Learning?
Types of Machine Learning (Supervised, Unsupervised, Reinforcement)
Difference between Linear Regression and Logistic Regression
They also asked me to draw and explain the Sigmoid Function graph
Finally, the HR asked if I was ready to relocate and open for a support role.
Overall Experience:
The interview was moderate in difficulty. The panel was friendly and focused on testing both basic programming and core ML understanding.
The interview is very difficult. Mostly they asked about my projects and asked questions which I didnot mentioned in my resume. Asked about scenario based questions. The interview went upto an hour.
