Master Huawei OD Interview: Complete Process, Tips, and What to Expect

Huawei OD Interview Process

Huawei OD’s interview consists of five distinct stages. Apart from the online test, the order of the remaining stages may vary, and the whole process typically takes about one to two months.

1. Online Test

Duration: 2.5 hours

Number of questions: 3 algorithm problems (2 easy, 1 medium)

Score composition: 100 + 100 + 200 = 400 points

Passing standard: Generally 150 points, but some departments or schools require higher scores

The online test is a critical gate; scoring below 150 usually means elimination, while scores above 260 provide a safety margin.

The test link is valid for 7 days; you must complete it within this period. You can only take the test once every six months; a failed attempt forces a six‑month wait. Ensure your device is set up correctly (camera, screen recording, latest Chrome, etc.). Keep the monitoring program running; any cheating or plagiarism invalidates the result. Contact HR promptly if any issues arise.

Targeted algorithm training can help candidates achieve scores above 300, securing a strong position.

2. Comprehensive Assessment

This is essentially a personality test lasting 20‑30 minutes. It is not a formality; candidates should answer positively and sincerely.

Allocate at least 30 minutes to complete it carefully. Choosing “always willing to work overtime” improves chances; refusing overtime often leads to elimination. Avoid contradictory answers and extreme options. If you fail, you must wait 18 months before retaking.

The assessment evaluates stability, attitude, and cultural fit.

3. Technical Interview

The technical interview is the most decisive stage, usually comprising two rounds (technical‑1 and technical‑2). It focuses on:

Algorithm and coding ability (live coding, problem‑solving)

Core knowledge (“八股文”) —must be familiar but not the main focus

Project experience —role, challenges, solutions, and design decisions

Algorithm skills set the lower bound for passing, while core knowledge and project depth determine the final rating and salary.

Typical project‑related questions include: Why did you design the interface this way? How would you prevent database deadlocks under high concurrency? How do you handle order failures and compensation? How to avoid overselling during high‑traffic ordering?

Deep project knowledge outweighs rote memorization of theory.

4. HR Interview

Although technically easy, the HR interview assesses motivation, stability, and salary expectations. Common topics are:

Why are you applying for this position?

Do you have other offers?

What salary range can you accept?

What is your view on overtime?

Demonstrating clear career goals and a realistic attitude is essential; vague or arrogant responses may lead to rejection.

5. Supervisor Interview

This round evaluates overall suitability and potential for growth, focusing on communication, teamwork, and alignment with the department.

What abilities are required for a developer?

What new technologies have you learned recently?

How do you relieve stress?

How will you quickly adapt to the role?

Which skills do you feel you lack?

Even if this stage fails, candidates can often transfer to other departments.

Future topics may include the difficulty of converting to a regular employee after joining Huawei OD.
