I applied online. I interviewed at Box (Warsaw, Masovia) in Oct 2025
Interview
Had worst experience ever. Extremely frustrating and a huge waste of time. Applied for a Senior Software Engineer role via LinkedIn. Completed three 1-hour interviews (coding, data structures, system design) and received very positive feedback from the recruiter, who said I was the top candidate. Asked me to hold on as she was looking for right fit as 5-6 teams were looking for Senior engineer. Guess what, suddenly all those positions were closed (extremely weird), and I was told they’d contact me for future openings. Months later, when a position opened no one contacted, I had to reach out to the recruiter to get scheduled for final onsite interviews - cultural fit, retrospective and hiring manager. After two weeks, I received an automated rejection email with no explanation, despite clearing all technical interviews.

At first I applied via job board, then recruiter screening, one week leater System design interview and Coding interview. I get declined at this step with quiet big feedback. All take around 3 weeks. And meeting in summarize was 4 hours.
