Arauco interview questions

Interviewed at Arauco and wanted to share my experience for anyone going through the process. The screening call was pleasant and a bit more detailed than your typical first-round — they asked specific questions rather than the usual high-level overview, which I actually appreciated. It set a good tone. The manager round was equally comfortable. He was calm and approachable, mostly trying to gauge whether I could do the work. Some behavioral questions, nothing unexpected. Then came the final panel round, and this is where I'd want to give future candidates a heads-up. The panel walked in with papers in hand, looking a little disengaged from the very start — it set a strange energy in the room right away. But the bigger surprise was the format itself: after two rounds with zero technical questions, I walked into the final round fully prepared to get into the technical weeds. Instead, it was back-to-back behavioral questions the entire time. "Tell me about a time..." all the way through. I wasn't mentally set up for that, and it showed. I fumbled through answers I could have nailed with the right preparation. So the advice is simple: do not assume the final round will be technical just because the earlier rounds weren't. For a data role, it's easy to over-index on technical prep and under-prepare your STAR stories. Have your behavioral answers as ready as your ML concepts. Overall a smooth enough process — just go in ready for anything.

Phone interview. Typical questions. Nothing out of the ordinary. They followed up via email afterwards. Very conversational type interview. Asked about current work, sales experience, travel requirements etc. overall positive experience
