I interviewed for a data analyst position today. The interviewer asked the following question:
If you are a restaurant owner and want to promote yourself on Dianping, how can you operate your own shop from the perspective of data analysis?
Here’s his answer:
1. Understand relevant SEO rules of the website, conduct keyword optimization and launch new ads in different periods, etc., and then try the effects of different advertising operations, and compare relevant ROI indicators for later optimization
2. Member system management based on RFM analysis method after drainage
3. Make timely supply chain adjustment based on people and goods yard analysis method
4. Consider opening branches after accumulating original capital
After hearing me out, the interviewer said the answer was dull.
Is there really no bright spot? Do you want to know the answer with bright spot?
At present, I can think of the optimization point is:
1. Product category problems, climb the website restaurant distribution and customer preferences to determine the hotel positioning
2 if the restaurant category has been positioned, collect user portraits of relevant seed users and recommend them to groups with similar user portraits
Community discussion and arrangement
1. A joking answer (just for fun, not to be used in an interview)
Me: Interviewer, do you really want to hear the highlights?
He: yes! Tell me what you really think. Impress me.
Me: Well, let me briefly say that, in fact, using data analysis will only narrow your thinking and stay in the convex nature of supply and demand competition.
He: Why? (I don’t think he understands what I’m saying.)
Me: Convexity is defined as the measurement of the curve between price and yield, which is simply a question of pricing and turnover rate.
He: Why does it narrow?
Me: Suppose a shop supply coffee and other competition differences are not big, that is, the supply is greater than the demand, then you do promotional activities, large cup coffee as long as 1 yuan, at this time the turnover rate will be high scary.
He: What does that have to do with narrowing? (He really doesn’t understand.)
Me: Because the final measure is the same, as long as the price is low to an extreme limit, it can destroy the imbalance between supply and demand. So you just have to think about whether your pockets are deep enough and what other benefits this drainage will bring.
He: Go on!
Me: Want me to continue to say words have to charge.
He: are you…
Me: Knowledge is worth a price, especially insights gained by rubbing them together. I came to you for an interview at my own expense and offered my insights, but I haven’t gained anything of substance yet, even a verbal commitment. So are you going to hire me?
2. Give a serious answer
