Round: Technical (DSA)

Date: 4th April 2026

Type: Hiring Drive

Difficulty: Medium-Hard # Context Attended a Tekion hiring drive on 4th April 2026. This was the DSA/Problem solving round. The interviewer gave a real-world design problem around a policy engine — something very relevant to Tekion's domain (automotive retail / DMS platform where configurable business rules are common). # The Question Design a

Policy Engine. We define a list of policies where each policy contains a condition expression (combination of AND/OR operators over field comparisons). Given a policy ID and a data object,

return

ALLOWED or

DENY. # What was asked specifically: 1. Design the data model for: * Policy (id, condition tree) * EvaluationRequest (policyId, data) * EvaluationResponse (policyId, decision) 2. Write code for the policy engine that evaluates the conditions and returns ALLOWED/DENY.

Sample Policy given by interviewer P1: { (creditScore >= 720 AND accountStatus == "Active") OR (receivableDays < 30) }

Sample Data { "creditScore": "750", "accountStatus": "Active", "receivableDays": "45", "annualRevenue": "600000", "yearsInBusiness": "5" } Based on policy ID and the data object, the engine should return

ALLOWED or

DENY. Hope this helps anyone prepping for Tekion interviews or LLD rounds in general!

About Tekion Interview Reports

This question was reported by a candidate who interviewed at Tekion. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.

Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Tekion are the higher-signal extractions to take from this report.

For broader preparation context, the Tekion interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.

How To Practice This Type of Question

Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.

Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Tekion reports consistently are the ones worth investing in; one-off niche problems are not.

During Your Tekion Round

Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.

The single most predictive failure mode in Tekion reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
