college life

Confused January-June

The first one was AsiaInfo, an intern of big data development who was interviewed. In this interview, I first introduced myself. There was a little stutter, and the project questions were answered. Overall, I still felt that there was drama, but unfortunately I didn’t receive it in the end. Notice, probably because of the spark they used, I only started to get in touch at that time, and I mainly learned Hadoop in school.

June-Dec with CSDN

Let’s talk about why I want to blog first. I have always used the Markdown editor to take notes. When preparing for interviews in June, I often look at me remembering notes before. Every time I export a PDF and send it to QQ to download it, it is too troublesome and wastes the memory of my phone. . Accidentally found that CSDN has a Markdown editor, so I started the road of blogging!

During the summer internship, I went home from get off work every day to watch video learning (reviewed the basics of java, newly learned data structures and algorithms, ETL development tool kettle), and then wrote a blog. During that time, I really took all the time to learn, because I My goal is to change jobs after I finish my studies, and then in September I felt that I had almost finished my studies, so I quit my job and went home to look for a new job for a month. Then I finished the advanced part of MySQL, SQL tuning (the interview is easy to be asked), and shell scripting. Everything I have learned is written on a blog for easy review! ! !Friends in need can look at the blog posted before, and the link will not be given here.

When I wrote my blog from June to September, I didn’t have a single fan. It started to increase in early September, as shown below:

It went up by 1000 in a month and I was so excited! ! !

After that, the fans have been rising, and I was fortunate to be on the list once!

Until December as shown below (I changed my name on impulse, and I have to wait a month to change it back, woo woo woo):

It’s very nice. Recently, because of my busy work, I mainly record some SQL and Python codes that are practical at work.

Ready for work experience

So I went to my current company for an interview. The position was a big data development intern. I prepared a lot of algorithms, SQL statements, SQL tuning, shell scripts, hadoop, and kettle tools. During the interview, I introduced myself and asked for Switching to Python, the company is relatively small, so I can’t use Hadoop at all, and the supervisor didn’t ask much about Hadoop, saying that if I am interested, I can build it myself from scratch, and they provide servers.
