The process is very time-consuming, and you might be rejected due to minor subjective perceptions from a single interviewer. The compensation offered is similar to or even slightly below other offers I received in Madrid. You will most likely not work on the core observability product but on other experiments they are conducting. For one of the teams I interviewed for, I would seriously question the product-market fit of their current initiatives. Therefore, think carefully if it is truly worth it.

The interviews are conducted late in the evening or at night due to the hiring team being located in a different time zone. You will only receive the final result after completing the entire process.

The process in detail:

1. Call with Recruiter
2. Call with Hiring Manager
3. In-depth presentation of a past project (prepare presentation beforehand)
4. Architecture Design
5. Delivery and Project Management
6. People Management and Leadership
7. Live Coding (LeetCode-level Easy-Medium)

All calls except the first one are one hour long, totaling 6.5 hours of interviews, plus a significant amount of preparation time. I managed to clear all rounds except for number 6. I was rejected because a manager several levels above the actual role, and who would never have worked directly with me, found that my description of team interaction lacked some detail.

Design a system that will distribute configuration data to remote agents installed on a large number of client hosts.

1. From a logfile, show the top N most frequently occurring IPs with their count.
2. Implement the Caesar cipher.
