2sigma 文化很push 嘛？待得会很不舒服嘛?

萝卜青菜吧，个人感觉想做技术专家/经理路线还是在科技公司，去金融公司就做交易之类的核心业务

楼主能不能发个circle的面经贴？我也在准备面这家，约了两轮design，一轮pair programming，一轮vp，一轮HM….感觉压力山大

大佬最后去哪家了？

This is a system design question in which you'll be asked to design a system that stores some timeseries data for output to a CSV.
You should just sketch out a system for storing the data; you do not need to actually implement it. This might model a system for recording sensor readings from IoT devices, or monitoring a large quantity of servers. You should focus on scalability, reliability and performance.
Imagine we have a data source that produces some timeseries data, In particular, each time the data source produces data at a given (t), it produces an ordered tuple (Xt1, Xt2,..., Xtn), where each Xti is a 32-bit integer. Let's suppose the data is produced every 10ms, and n (the size of the tuple) is 1000. Thus, there are 100 (Xt1, Xt2,...., Xt1000) tuples produced every second.
To query the data, your system will be given a (t0, t1) pair, for which, you must produce a CSV containing all data recorded between t0 and t1. Each row will always contain all n data points sampled at a given t, and thus will have n + 1 columns (since the first column is for t). The first row is a header for clarity.

You should expect (t0, t1) to be fairly large (months or years)
Thus, in sum, you should design a system that provides two operations:
* Record(t, Xt,1, Xt,2, .... Xt,n), which doesn't return any data. It is called every 10 milliseconds to add data to your system.
* Query(t0, t1), which returns a CSV as described above. It is called to produce CSV.
Your interviewer may add constraints or requirements once you finish an initial design, so try to build something as simple as possible first and then iterate.

这些就是一些基础知识吧 hash的java接口 你也可以google看看 没有什么特别的 我只是觉得这种考法挺八股的

了解了，原来问这种比较基础比较specific问题让面试者觉得“面试官知识很薄弱”，以后多注意一点

今天终于够分看楼主的贴了，感谢楼主，分享的很好。

大佬太强了！关注面也很广！
