How long does the Trendyol interview process take?

Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.

How should I prepare specifically for Trendyol?

Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.

Does this apply to engineering or design roles at Trendyol?

The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.

Type · hard-coding
Implement a function to find the shortest path between two products in a 'related products' graph. The graph is represented by an adjacency list where each edge has a weight representing the similarity score. Use Dijkstra's algorithm or a similar approach.
7
Type · debugging
Here is a piece of code that is supposed to calculate the total price of items in a shopping cart, applying discounts based on product category and user loyalty status. It's producing incorrect results for certain edge cases. Debug and fix it.
