I applied online. I interviewed at Zendesk (Lisbon, Lisbon District) in Jun 2025
Interview
3-4 interview rounds. HR, EM & Tech Lead(s). Interview is realistic, and focuses more on knowledge basis than fancy algorithmic resolution of problems, evaluating pros & cons of a solution.
Interview questions [1]
Question 1
aabbcc -> a2b2c2. Second part, aabbccab -> a2b2c2a1b1 (most people use dictionaries on the first question). Relate solution to efficiency & memory.
