JPMorgan Interview Experience for SDE

Round 1:

After a brief introduction, they asked me to describe my 2nd-year internship project. As it was based on Machine Learning, the interview started with questions from ML. I was asked to give a very intuitive definition for ML so that anyone who doesn’t know ML can also understand, followed by detailed and conceptual questions on regression, deep learning and CNN layer related parameters. Then there were 2 coding questions. One was from DP and I don’t remember what the second question was (Probably Trie based). I had a research paper from my internship so we went on to discuss that.

Round 2:

Here I was asked to explain my 3rd-year internship project. Then there was a data structure based question, where I had to design a notepad-like application with few features (returning the word number on using find command, editing or deleting words, and few others). I provided my approach and they were satisfied so they asked me to write the class on paper. As I was going in the right direction, they told me it is fine and we started discussing doubly linked lists and hash maps. Most of my projects were computer vision-based so they asked me a related question: Suppose you are provided with election voting papers in which voters have put their respective seals in front of their preferred candidates. Now you have to count the number of votes to each candidate. I started with Haar-cascade, which they weren’t sure would work, so I explained my approach. After a very lengthy discussion, I was asked to write my code on paper.

Next, they asked me about my PORs and my individual contributions to Alcher. They specifically asked what was the main difference in my way of approach than previous ones that brought the results.

Round 3:

This round was with a VP. It wasn’t technical but rather an informal one. As I was getting calls from other companies, he told me that I can relax now as I am already selected based on my reviews from technical round. We had a very interesting discussion on mathematics, books, probability, life in IIT, etc. He also asked me to solve a mental mathematics problem with a timer on.
