Sia Partners

End-to-end, Sia states the recruitment process runs around four weeks on average, with the option to compress it where needed. Interviews are run in Sia's offices by default and offered by video conference for candidates abroad. The Business Case sits at the centre of the loop, so a candidate is committing real case-method preparation time well before serious interviews start, rather than turning the firm round on standard behavioural prep alone.

Sia's careers page describes two main early-careers tracks, recruited from top universities, business and engineering schools throughout the year:

• End-of-studies internship – a six-month placement aimed at hiring onto a permanent contract, where Sia states roughly 90% of interns continue at the firm after their internship.
• First Employment (permanent) – direct entry on a permanent contract for new graduates who have already completed an internship in consulting or in one of Sia's sector or service specialisations.

Candidates pick and apply to a specific Business Unit at application, and new joiners complete a three-month onboarding programme supported by a field tutor and an HR representative. The 90% intern conversion rate means the end-of-studies internship is the primary pipeline into permanent consulting work at Sia – a candidate routing through it is effectively applying for a permanent role with a six-month preview, not a short summer stint to brand-build.

A few structural features set Sia apart from a generic mid-tier consultancy:

• An AI-heavy capability footprint inside a management-consulting firm: roughly 450 data and AI consultants sit within Sia's ~3,000-person bench across 48 offices in 19 countries, and the firm publishes a productised line of deployable AI agents alongside client advisory.
• A rolling, year-round hiring pattern rather than a fixed graduate cycle: the recruitment page advertises continuous intake of new-graduate and intern applications and does not publish season-bound deadlines.
• A published intern-to-permanent conversion rate of roughly 90% on the end-of-studies internship.

For a candidate weighing Sia against the Big Four consulting arms, the trade-off is concrete: materially smaller and more digital-/AI-tilted, with an internship that functions as a long permanent-track audition rather than a brand-on-CV summer stint – and an application timeline that is not pinned to the autumn graduate window.
