• Analyze unfamiliar problems and translate their requirements into implementable solutions.
• Select appropriate algorithms, data structures, and problem-solving strategies.
Required Qualifications
• A Codeforces profife is a must
• Strong understanding of common data structures and algorithms.
• Ability to reason carefully about constraints, complexity, edge cases, and correctness.
• Experience debugging unfamiliar code or solving technically ambiguous problems.
A public or otherwise verifiable Codeforces profile demonstrating meaningful competitive-programming experience is nice to have.
Process
• Apply to the role and complete the screening questions.
• Complete an AI interview of approximately 30 minutes.
• Complete the hiring manager review.Compensation Structure
Compensation is output-based. Experts are paid per task that meets the project specifications. The time required to complete each task may vary depending on the expert’s experience and workflow.
Minimum submission requirements apply.
