Candidatei-me por meio de recrutador(a). Fiz uma entrevista na empresa Amazon.
Entrevista
First, there was an online coding question, which was not easy.
Then there was an onsite interview. Generally simple questions over 4 technical rounds.
Questions:
1 Print all the elements in an array that have occurred an odd number of times
2 Design a Chess game
3 Design a Parking Lot
4 Given an array of stock prices, where the increasing indexes of the array signify the increase in time. Return a good time to buy and sell such that profit is maximized.
5. Given a Linked List, split this linked list into 2 lists such that one list contains only odd numbers and the other one contains only even numbers
6. Find the square root of a number. Optimize.
Surprisingly easy — I expected tougher questions, but the coding round felt more like a warm-up. The main challenge was a DSA problem about counting islands in a 2D grid, which led to a discussion on DFS versus BFS and handling large grids. Funny enough, I had revisited that exact type of question while prepping on PracHub, which made me feel more confident. The interview wrapped up with a behavioral round, and I accepted an offer, but ultimately decided to decline it for another opportunity. Overall, it was a smooth experience.

Pergunta 1
Number of Islands — given a 2D grid of '1's (land) and '0's (water), count the number of connected islands. Walk through DFS vs BFS, and discuss how to avoid revisiting cells (in-place mutation vs visited set) and what changes if the grid is huge and must stream from disk.
It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.
