Application is a CV plus a mandatory 'statement of exceptional work' — reviewed by engineers, not recruiters. Then a 15–30-minute phone screen with an engineer, and a main loop xAI's own job postings target to finish within ONE week: a coding assessment in your language of choice, two role-specific technical deep-dive sessions, and a 'Meet the Team' round where you present your exceptional work and your vision for xAI to a small audience. Coding is applied class design (key-value stores with transactions, LRU caches, iterators) that hardens via mid-problem extensions — completeness and bug-free code beat big-O talk — and design rounds demand working code in the same session. There is no dedicated behavioral or values round; decisions land within days with no hiring committee. Some loops run all-remote on Google Meet, others add an in-person Palo Alto onsite.
