2. Online Assessment / Coding
Timed - algorithmsA coding/quant OA: sliding-window and DP problems (cheapest roof covering k cars, subarray optimization).
3. Probability & Mental Math
45-60 min - videoProbability, expectation, combinatorics, and brain-teasers -- card-guessing EV (harmonic numbers), races, counting.
4. Statistics
45-60 min - videoStatistics and regression brain-teasers: duplicated-data effects on slope/R-squared/t-stat.
5. Onsite - Hardest Rounds
Final rounds - the toughest reported problemsThe hardest reported GTS problems across every topic. (Hard-rated only; earlier rounds cover easy/medium, so nothing repeats.)
