How long does the GravitHy interview process take?

Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.

How should I prepare specifically for GravitHy?

Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.

Does this apply to engineering or design roles at GravitHy?

The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.

3
Round 3
Forecasting & Planning
Demand planning, S&OP, inventory optimization, working with statistical and ML forecasts.
4
Round 4
Optimization
Linear programming intuition, route optimization, facility location, trade-offs between cost/service/CO2.
5
Round 5

The Danger Zone: Top Reasons Candidates Fail

Based on our database of GravitHy interview outcomes, avoid these common traps:

Inability to quantify the impact of their optimization efforts.
Focusing only on transportation costs without considering lead times, risk, or CO2 emissions.
Not identifying relevant external data sources for an emerging market.
Focusing solely on distance without considering delivery time constraints or vehicle capacity.

Test Yourself: Real GravitHy Questions

Three real prompts pulled from our database.

Type · case-study

Imagine GravitHy is scaling up production and needs to establish a new distribution hub for its green hydrogen. Walk us through the key factors you'd consider in selecting the optimal location and designing the network.
