I applied through a recruiter. I interviewed at Glovo (Barcelona)
Interview
I didn't pass the first call, the interviewer was really nice and friendly, he asked about my experience and my current position responsibilities.
The email had no feedback, they simply say sorry and some other stuff about the company.
The interviewer didn't seem to understand the questions and he approved all answers without any comments.
I don't really memorise googleable information, the sort algorithms question is really not very good, I mean the O(n) can be memorised but only among competitive programmes and university students, since they use them all the time, a senior engineer is expected to solve higher level problems and this information is something that you rarely use, unless you are working on special systems like compression programs of image processing.
The interview directly reflects the nature of the engineers that work there, they want competitive programmers, seems they lack framework and system design experts and prefer hackerrankers
Interview questions [1]
Question 1
Q1: list some Data Structures that you know.
Q2: list http methods that you know and define them.
Q3: Explain what is HashTable collision.
Q4: list sorting algorithms that you know with the time complexity of each one.
Had a call with the HR manager, he introduced the company and its plans, asked about my motivation and experience. The conversation was friendly and polite. I received clear answers to all my questions. However, I didn’t feel any particular interest in me as a candidate. One of the questions seemed a bit suspicious, what would I do if a production issue occurred on a Friday evening.
The response from the company came the next day, automatically, from a no-reply address. That made it impossible to ask for immediate feedback or any follow-up questions.
To me, receiving an automatic response from a no-reply sender is somewhat telling about the internal culture.

I applied online. The process took 1 week. I interviewed at Glovo (Barcelona) in Apr 2025
Interview
Leetcode-style question with a clever twist, incorporating unique constraints and edge cases. The solution includes thorough unit test coverage and insightful discussions on multi-threading, concurrency control, synchronization techniques, potential race conditions, and performance trade-offs in real-world, production-grade scenarios.

Interview
I had a two-step interview. The first was a casual chat about my background and what I’m looking for. The second was a live coding session with a medium problem, followed by questions on time and space complexity and how a HashMap works under the hood
