Ericsson·Software Engineer·Onsite - Coding / Algorithms

Jun 2026

Ericsson software engineer coding round, two problems back to back in an hour. Nothing too wild but the heap question required you to actually know your data structures, not just fake it.

Given an integer numRows, generate the first numRows rows of Pascal's triangle and return them as a list of rows.
Given an array of integers and a value k, return any k values that appear most frequently in the array.

“Knew this one the moment I read it.”

Coding round at Ericsson for a software engineer role, pretty straightforward from what I can tell. Just the one problem and it was a classic.

Generate Pascal's Triangle up to n rows.

“Straight from LeetCode, no modifications.”

Went through a coding round at Ericsson for a software engineer position. Just one algorithmic problem but it was enough to keep me busy for a bit.

Given an array of integers, find the k most frequently occurring elements.

“Classic frequency problem.”
