Interview
I interviewed for the Senior Software Engineer role in London. The full process ran about six weeks and was seven interviews in total:
Recruiter screen with Emily
Round 1 — hiring-manager conversation
Round 1 — 60-min live coding interview (language of your choice; mine was a string/anagram problem in Go)
Round 2 — system-design session on a virtual whiteboard
Round 2 — technical discussion where I presented an impactful project (~15 min) followed by Q&A
Final round — ~30-min conversational "leadership discussion" with an engineering EVP about background and long-term goals
An added meet-and-greet with the engineering manager I'd report to — a new manager who had just joined, so they tacked this on as an extra, final round
Kudos to Emily, the recruiter — she was communicative, warm, and fast at every step, set clear expectations, shared specific written feedback after the decision, offered a wrap-up call, and even went out of her way to pitch me to other teams at Docker afterwards. One of the best recruiter experiences I've had.

Question 1
Walk us through an impactful project you led, the trade-offs you made and what you'd change in hindsight.

Interview
Only got as far as initial screening. Rejected after a month with the "we have gone with other candidates" line, but at least they get back to you (eventually) instead of ghosting.
