product analytics/ sense 跟踪记录贴

谈不上总结。刷题日记。 来自B2B的怪物要熟悉 2C的世界了

一点点记录下来 自己看的资料和感想。以后再整理

之前面analyst 的帖子。http://www.1point3acres.com/bbs/ ... p;extra=#pid2587312

现在已经做了一年PM 在面PM神马的

系统知识理论 和 解题并进 感觉都是套路

之前面Anlyst的时候很多东西想不通 也找不到 原来都在Pm面试里面

现在只能零散的记录 以后出一份中文的专门给数据的童鞋

晕。好像最近Apply出错超级多 self management 备受质疑啊
还是要端正态度

我记得FB好像也有这种东西

Position Overview

As an overview, our Product Managers bring to fruition new products and features that genuinely benefit our users while at the same time make good business sense. They act as general managers of our products, providing leadership across functional teams to conceptualize, build and deliver Google's next great app. Product Managers find our entrepreneurial culture to be exciting and challenging, because they are never stuck maintaining an existing product, but are instead focused on developing new product ideas and strategies.

We have openings across all of our products in areas such as Consumer, Mobile, Apps, Enterprise, Infrastructure and Hardware to name a few. As a brief outline, we have an agnostic interview process in which we aim to hire Product Manager "generalists", who may have niche experience but can easily float through our evolving product lines. We find this keeps our Product Managers fresh and with distributed, homogeneous experiences for our project teams. So, in a nutshell, we do not hire for a specific product, but rather, are seeking generalists who can work on multiple products. As such, you'll interview with Product Managers working on any number of our various products. At a later point, our leadership reviews your interests, background and interviews to identify relevant projects that align with business need.

Interviewing @ Google

Interviewing for a new job can be scary and intimidating. At Google, we hope they’ll be challenging and enjoyable. As we aim to hire generalists, you can expect to interview with Product Managers working on any number of our products - our Product Managers are centered on problem solving ability so there won’t be many questions about specific experiences or domains.

In preparation, you can expect discussions around the following:

*Product design - Thinking creatively/critically about products - eg, how to monetize twitter, how to change Gmail, design an app for the Louvre. Give feedback and analysis on features (think of how to best delight the user), technical design, UI design.

*Product strategy - Understand Google’s competitive landscape and discuss the vision for Google, the mobile market, the ad market, the internet, and technology in general. Discuss long term product roadmaps & strategies to increase market share.

*Analytical - May be a market analysis, problem solving or brain teaser question, eg. How would you store all the phone calls in the world? Most important is attention to detail and communication of how you’d break the problem into smaller nuggets to reach an overall solution.

*Technical - You could be asked architecture/design (eg multi-tiered web apps, data storage in databases) or conceptual questions (eg internet technologies and protocols). Possibly even an algorithm/coding question or two.

How can I prepare for interviews?

如何刷pm的题呢

今天的系统知识 已经更新在了旧帖子里
我还是觉得 就算是数学的同学
面Case的时候 也必须 Think as PM
Pm就必须think as 大老板 所谓拿着买白菜的钱 操着卖白粉的心

那今天差不多结束 拿两个题练练

Tell me how you would scale a social media software platform?framework : AARRR

Asked me how I monetized a mobile app which I had supervised. Kept digging on this issue even though I've plainly stated that I couldn't figure out an effective way to monetize a socialization-based mobile app. The flow of the interview got to a snail's pace.

补充内容 (2016-10-18 16:29):
PM's primary objective is to build a product that achieves or strives to achieve one or more stated business goals. For monetization - customers are paying for silly and elementary services like note taking and even turning their smart phones into a glowstick/flashlight. You should have at least tried to think of a few possible ideas.

好多奇葩问题
What is the marginal cost of a gigabyte in gmail?
边际成本？。。。。。 gmail
好像是个Pricing问题 相当于说 如果要加容量 1G多少钱这样
怎么定价么？

Here's my guess at what they're looking for. Marginal cost - this is the additional cost for adding a user. It doesn't need to take in to account the software development effort, but it should take out the atomized cost for everything else. You need to price out the the cost of the enterprise HD/GB. We can call it $1 by GB. Then you need to realize that there needs to be redundancy, so at the lest we need to double that number, if they put a super high value on data retention triple it. Then you need to think about server cost and divide that out, server rack space cost and physical rack area...etc. So if it's $1 for the actual HD space it's probably more like $2.50-$3.50 for the total marginal cost. I don't work for google, but my guess is that they're looking at the though process. What will change with a marginal user increase and what will not. If you only think of the cost of the HD then you're not getting a job with google.

我要瞎了。。。

you are on a biz trip and travelling from one city to another. you have a stack of unsorted flight boarding passes. only departure city and destination city are on the boarding pass. how do you find the first departure city and your final destination city

What would you do to double the revenue for an existing Google product in the next 12 months?

I would ask the interviewer to clarify the question by: - what specific product - what are the current focused segment of the product - to increase revenue, you need to either find other focused segment (i.e.,e adjacent market) or increase market share in the current focused segment - if you already have large mkt share, then it is best to focus on creating solution for other focused segments

Enter new markets or segments, look at your LTV and focus on growth within the highest LTV segment (repeat engagement / purchases).

We dug deep into at least 3 monetization methods we've undertaken:
1. Back-end photo printing service (revenue share with printer) given that our site stores photo albums. 2. General display ads. 3. Location-based ad (based on locations photos were taken).

We got deep into the discussion, just falling short of details such as percentage of revenue share, display ad click-through rate, etc., which I consider trade secrets even though I'm no longer associated with that company.'s operations I grew frustrated as the interviewer only seems to be interested in what we did, what succeeded and what failed.

He was not interested in learning more about me. I tried several times to guide the discussion back to myself and what I might contribute to Google, but to no avail.

Given a set of 2D coordinates for the 4 corners of each building in a city skyline (as if in a photograph), how would you determine the outline of the silhouette of all buildings, where buildings may or may not overlap?

这是JS题么。。。。

Suppose there is a smart phone API that can give you a person's mood and that there are 100 different moods. There can be varying level of moods, such as happy, very happy, sad, extremely sad, etc. You can also have more than one mood at a time (such as nervous and excited). What app would you create to take advantage of this API?
