At SimilarWeb I met the worst interviewer in my career. Usually, you expect interview be a friendly polite talk between candidate and company employees. That's not the case for SimilarWeb. Prepare yourself for solving technical questions without written description (only weak schematics), also prepare to decode what interviewer wants from you (there is no written description remember). Finally, don't ask the interviewer to repeat the task, they don't have time, they are busy eating, because apparently listening to other person chewing improves your thinking process. Also, be ready to finish your interview 40 mins sooner solving 2/3 questions, because interview is "Already got everything what he needs :)". Any questions to me??
