How recommendation systems in popular apps shape attention, preferences, and the information we consume.

Thanks to a referral from senior schoolmate @lxc, I had the opportunity to go to Microsoft Suzhou and interview for a summer internship in the O365 department. Although I failed in the end, I learned a lot from this failure.
I am summarizing it here to prepare for future internship and job hunting.

The following commands are only for Unix-like systems.
Windows does not need this solution. Many PuTTY-like tools on Windows can choose “remember password” to implement passwordless login.
I did not find a similar password-remembering solution on Mac, but using a key is actually a more secure method.

This week at the company I wrote many long and functionally complex SQL statements. I deeply felt that my database and SQL knowledge was still only superficial and completely unable to meet engineering requirements.
The second mentor responsible for guiding me is also quite proficient in SQL and gave me a lot of guidance and suggestions.
Without comparison, there is no hurt. Seeing how weak I was and how strong my senior schoolmate was made me feel ashamed and then determined, so I developed the idea and action plan of advancing my SQL skills.

I used Tencent Cloud’s free domain name.

In addition, some settings are also needed on GitHub. You can refer to the official help document.

Thanks to senior schoolmate @lxc for the referral and interview advice, I was fortunate enough to attend the interview for an algorithm intern role in Kuaishou’s recommendation group, and I eventually passed the interview and received the offer.
Although intern interviews may be relatively simple, I think this still has reference value.
Doing internships can be considered one route toward eventually finding a good job and joining a dream company. It cannot really be called a shortcut; the two internships I did were both quite tiring. Kuaishou was my second internship.
Now that the internship has finally stabilized, and there is still some time before the deadline for my graduation thesis, I happen to have time to summarize my interview and internship.
I hope this can guide my future search for other internships or full-time jobs :)

I used LaTeX to write my graduation thesis and encountered many problems. I summarize them here.

Problem Description

Three months ago, I came to Oushu Technology for an internship. Both studying and working used the Mac provided by the company. You get what you pay for; the Mac really is much easier to use than the 5000 RMB HP laptop I bought in 2015. So besides work, my study tasks and lab tasks also gradually migrated to the Mac. Now I have encountered a rather tricky problem: how to keep my work GitHub account from conflicting with my personal account while still using both conveniently.

After looking through related materials, I implemented the following solution.

# lunch jupyter QTConsole with specific kernel
jupyter qtconsole --kernel=py27
