How do I know which BCG assessment I'll get?

The invitation email from BCG's recruiting team names each module and links to the platform. Different offices pair modules differently, and BCG rotates formats every recruiting cycle.

Which is the most common BCG assessment format?

Casey — BCG's chatbot case — is the dominant module worldwide. It's usually paired with Pymetrics in the US and EU, or with the Cognitive Test in DACH.

How long does the full BCG Online Assessment take?

Most candidates spend 60–90 minutes of test time in total. Add setup and camera checks and you should block two hours.

How is the BCG Online Assessment scored?

Each module is scored independently — automated first, human review for shortlisted candidates. There is no single composite score you ever see.

Can I retake the BCG Online Assessment?

Almost never within a recruiting cycle. Most offices enforce a 12-month cooldown before you can reapply.

How much should I prepare?

Two to four weeks of focused practice is enough: a handful of full Casey simulations, one or two Pymetrics dry-runs, and — if you're in DACH — 200–300 Cognitive Test items.

Where should I start?

Confirm which modules you'll take from your invitation email, then read the pillar guide for each. Practice the highest-weight module — usually Casey — first.

BCG Online Assessment — Which Test Will You Take?

Q: What is the BCG Online Assessment?

A digital pre-interview screen built from several modules — the Casey chatbot case, Pymetrics games, the Cognitive Test, and in some offices the CCA or the legacy Potential Test. Total content is usually 60–90 minutes.

BCG doesn't use a single test. Depending on your office, role, and recruiting cycle you'll face one of five formats — Casey, Pymetrics, Cognitive Test, CCA, or the legacy Potential Test. This hub maps every format and points you to the right prep path.

What is the BCG Online Assessment?

The BCG Online Assessment is a digital pre-interview screen delivered in modules. BCG picks the mix per office and recruiting cycle, so no two candidates take exactly the same test. Most candidates spend 60 to 90 minutes of active test time across two or three modules.

The 5 formats compared

Assessment	Format	Length	Regions
Casey	AI chatbot, linear	25–30 min	Most global offices
Pymetrics	12 behavioral games	~25 min	Many US + EU offices
Cognitive Test	80 questions	30 min	DACH region
BCG CCA practice	Behavioral + math	~45 min	Newer markets
Potential Test	Legacy paper-style	45 min	Mostly retired

How BCG decides which assessment

Three factors:

Office. DACH offices lean Cognitive Test. US/EU offices lean Casey + Pymetrics. Newer markets pilot the CCA.
Role. Consultant-track roles get the full stack. Specialty roles (Digital, Platinion) sometimes skip Pymetrics.
Cycle. BCG rotates modules every 12 months — this year's mix isn't necessarily next year's.

Which module to prep first

If you're unsure which mix applies: prep Casey first. It's the dominant module worldwide, has the highest score weight, and the case-thinking skills transfer to the human interviews.

Prep sequencing

Week 1: Read the pillar guide for each module you'll take.
Weeks 2–3: Full timed Casey simulations. Add Cognitive Test drills if you're DACH.
Week 4: One Pymetrics dry-run + one final Casey dress rehearsal.

Timeline from application to onsite

Week 0: Application submitted.
Weeks 1–3: CV screen and — if you pass — online assessment invitation.
Weeks 4–6: Online assessment window (typically 7–14 days from invite).
Weeks 6–8: First-round interviews for candidates who pass.
Weeks 8–10: Partner-round and offer decisions.
