A&O Shearman operates a hybrid assignment system, summer associates select two practice groups for rotations but can also explore work outside those groups through a centralized assignment database, offering both structure and flexibility. Interviewers focus on getting to know candidates as people rather than running through credentials mechanically. The callback process typically involves a one-hour screener followed by a two-hour callback, and candidates report that the atmosphere is conversational and genuinely welcoming. The firm invests in professional development through structured training academies and cross-border secondment opportunities.

The A&O Shearman merger combined two firms with storied histories. Allen & Overy was founded in 1930 and helped draft the Marshall Plan, while Shearman & Sterling counted Jay Gould and James Fisk among its earliest clients. The resulting firm gives associates the rare opportunity to work within a truly integrated transatlantic platform from day one, with the institutional knowledge of both Magic Circle and White Shoe traditions.
