Sift Senior Software Engineer interview questions

Tech screen with LeetCode style question then virtual onsite with Coding, Sys Design, Deep Dive, Behavioral. During one round in virtual onsite, the interviewer had to step away for 5 to 10 minutes. Giving me less time to solve the challenge. Which I felt was unfair and out of my control. Having less time is why I feel like I did not get an offer due to having less "done" in comparison to other candidates. It didn't matter to me too much anyway as I felt like there was an Offshore focused Work Culture. The Hiring Manager told me that the "offshore employees typically out performs the onshore employees." Which was really off-putting to me. I do not think I would want to work here anyway if there is such a strong preference for one over the other.
