Common Product Manager Interview Questions - Job Questions

Work issues

1. How long does it take to draw a prototype and how long does it take to write a PRD document?

Reference answer: Generally, a large prototype project takes about a month, and a small one can be completed in three or two days. Therefore, the progress of completion varies according to the size of the demand. It takes a long time to complete a product from zero to one. , Generally, the time required for function iteration is relatively short, and the same is true for documents. It takes longer to write more pages, and shorter time to write fewer pages.

2. What should be written in the market demand document?

1. market size
2. Future Trends of the Market
3. Competitive products in the market
4. Market opportunities
5. market capacity
6. Market opportunities
7. product problem
8. market description
   1. client subdivision
   2. Influencing factors
   3. customer target
9. Product Description

Reference answer: Market demand documents are generally a document written to analyze the market. There are several points in the written part, including market size, future market trends, competing products, product problems, market capacity, and customer segmentation. , customer goals and product descriptions, these parts need to be written.

3. How are user interviews conducted?

focus group

The first step: clarify the goal of the interview—for which requirement or function to conduct the interview

Understand user scenarios - in which scenarios to use

Define research methods

1. Questionnaire
2. one-on-one interview
   1. Designing the questionnaire
   2. Consult users on issues
   3. Develop a visit outline
   4. experience problem
   5. product detail question
3. Interview summary----classify and sort out the questions and determine the interview results.

Reference answer: first determine the objective of the interview, conduct interviews on a certain product or function, for example, you can do this type of interview after a new product is launched, and understand the user’s usage scenario, for example, in what scenario is this app used, Then determine the specific research method, which can be in the form of questionnaire survey or symposium.

In one-to-one interviews, it is necessary to design a questionnaire first, conduct targeted interviews with users, and formulate an outline, including interviews on product details. After the interviews are completed, it is necessary to summarize, determine the results of the interviews, and conduct summary analysis.

4. How is the questionnaire done and what are the results?

How to do it

step:

1. clarify the purpose of the investigation
2. Determine the scope of the investigation and the specific method
3. Collect questionnaires and organize them
4. summary question

Tencent Questionnaire—Online Questionnaire Survey Method

1. Design Questionnaire Questions
2. Aiming at a user interface experience problem
3. Several problems with the use of functions
4. Find out whether users like or dislike

Reference answer: Questionnaire survey We generally use online research method, online questionnaire is a more convenient form of questionnaire, usually we need to determine the purpose of the survey first, and investigate the doubts about a certain issue in product development, such as Say whether the user's needs meet this point, and then design targeted questions, design 15-20 general questions, collect basic information of users, including the results of user feedback, conduct data analysis, and draw conclusions.

For example, when making a report on the payment habits of e-commerce apps, through a survey of 1,000 questionnaires, it was found that users use WeChat more. Of course, there are other results, which need to be investigated according to the actual situation.

5. How are requirements collected? Where does the need come from?

Collection sources: market, operations, customers, users, bosses, feedback information, surveys

Collection method: collect and organize by demand pool

Reference answer: There are many sources of demand collection, such as operations, customers, users, and bosses, including some network feedback information. The product manager's own investigation is actually the source of demand. Mainly use the demand pool to sort out and collect, and summarize the needs into a demand pool table for management, because there are many user needs, it is necessary to analyze the authenticity of user needs, and at the same time, whether to do it or not needs to be analyzed.

6. How do you manage requirements?

Manage with Requirements Pool

management method

1. source of demand
2. requester
3. Request submission time
4. demand priority
5. demand importance
6. development status
7. Amount of development

Reference answer: Generally, the requirement pool management table is used. Because the collection of requirements is very detailed work, the requirements need to be managed in the form of tables. In the requirement pool table, we usually have these dimensions for management. The source of the demand, who proposed the demand, the time when the demand was submitted, the priority of the demand, the importance level of the demand, the development status, whether it has been developed or not, and the amount of development, these are the scopes that need to be managed by the demand pool. Every requirement must be entered into the requirement pool.

7. How do you prioritize?

Reference answer: There are several dimensions for priority confirmation. The priority is confirmed according to the three dimensions of importance, urgency, and demand value. Generally, each dimension is divided into five levels, and level 5 is the highest difficulty. Urgency is a key dimension
. Important and urgent matters are dealt with first, important and non-urgent matters are processed according to plan, unimportant and urgent matters are handled at any time, and unimportant and non-urgent matters can be processed in the next version.

8. How to schedule the project?

Project scheduling is generally done by the project manager. The project manager mainly does the project scheduling. We will also participate in the project scheduling. Generally, a demand review meeting will be held to arrange the personnel of the project for scheduling.

Clarify goals and scope

Break down work content for scheduling

output schedule

Allocate manpower according to plan

Reference answer: A review meeting is required to arrange the project personnel. At this stage, it is necessary to clarify the goals and scope, decompose the work content, assign it to each person, and set up milestones, precise time, and output the project schedule. Allocate human resources according to the person in charge.

9. How long does it take for a version update?

By version size

1. Large version - one month
2. Medium version—ten days
3. Minor version - a few days

Reference answer: Generally, it is carried out according to the version. The large version generally takes one month, the medium version takes more than ten days, and the small version can be completed in a few days. Therefore, the size of the version is different, and the update time is also different. Basically, in the work, the small version is updated the most, because it is all agile development and requires rapid iteration.

10. Do you know how to operate?

Reference answer: It cannot be said that they are proficient in all of them.] As product managers, we all need to participate. Product managers do not understand operations and cannot design products correctly. Product managers need to be heavily involved. The essence of operations is to attract new products, retain them, promote them, and transform these tasks. This is also the goal of the product manager. After the product itself is produced, it still depends on these data indicators. In fact, they are all in the same form, and operations and products have many similarities. So you need to understand some of them.

11. How to communicate with technology, how to communicate with UI, and how to communicate with operations

Reference answer: General technology does not have user thinking, they only have specific methods of implementation. When I communicate with technology, it is mainly about the implementation method of communication. So try to use technical terms to communicate,
and when communicating with technology, you will also encounter the situation where the developer’s project hits the schedule. In this case, the development schedule is based on priority.

The communication with the UI is generally a prototype interface, and there are more communication about specific pages, including design styles and requirements. and

Operational communication is mainly about needs. General operations will put forward various operational needs, such as doing some promotional advertisements. We have to understand them in detail. There are also some data-related issues that I also communicate with them, such as problems such as excessive churn rates, and how to improve the product will also be communicated. The operation is mainly to attract some new users, and to promote the activity of old users, to develop some operation plans and promotion plans. Check out some operational data. Write some promotional copy, manage product advertising.

12. How is product data collected?

Reference answer: After the product is launched, data will be collected in two ways. In the early stage, a third-party statistical collection data is used. Later, the data is buried, and the event will be buried in the product to count the key. Data, such as user click events, user paths, and user conversion events, all need to be collected. Data collection is actually for the preparation of subsequent data analysis, and each product must have data statistics.

13. What if the boss disagrees with your request?

Reference answer: First of all, you need to figure out why, figure out why the boss disagrees, convince the boss, use data to convince the boss, and do some research to give the boss a reference. If the boss still doesn't agree, then follow the boss's thinking and keep our current plan. The boss may also have his own ideas, such as profitability issues and business issues that we may not have considered.

14. How to convert user needs into product needs?

Investigate product user thinking and user needs

1. Analyze what user needs are
2. From requirements to functional design
3. What function meets the user's needs
4. What kind of solution can solve this problem
5. Cut into the pain points of users

Reference answer: From user needs to product needs, it is first necessary to analyze the user needs, what is the user need, why is there such a need, the demand put forward by the user may not be a real demand, for example, the user said that I want a navigation bar , In fact, this is only a superficial requirement. The deep-seated requirement is that he will find this browsing method inconvenient. From this aspect, we can say that the focus of product requirements is to solve the problem of inconvenient browsing information for users.

The starting point of product design should not be the solution of the navigation bar, but the convenience of browsing information. In this way, we can also make reasonable optimizations in the interface, such as enlarging fonts and turning pages, all of which are to convert user needs into The process of product requirements.

15. Why do you think you need to write a requirements document? Will the developers of the requirements document you write read it?

Reference answer: The requirements document is one of the very important documents for technical communication. The quality of the requirements document directly affects whether the development progress can be completed. Including logic, the process is written with emphasis, some technologies like to look at prototype development, some technologies like to read documents, there are different situations, the general technology is to look at documents, write more comprehensive and detailed, so that they Development can be carried out according to the requirements document.
