2022 Internship Interview Testimonials
- ByteDance Data Analyst 2022-8-3
First, self-introduction
and second, I gave me a sql question, which uses the group by grouping function, and it is best to nest a subquery. Then I came up with a question (it seems to be the direction of the product manager), saying that there was a video playback volume in Battle B, and suddenly one day plummeted in a month. From what aspects would you analyze it? My first reaction was to build other related Indicators, such as the number of likes of that video, the number of bullet screens and other related indicators. Then there were some problems that I forgot. - Bytedance Backend Development Engineer - Data Direction 2022-8-13
The first part is also to examine my sql ability, after learning the first lesson. Then I checked my basic knowledge of machine learning and asked me what is the difference between GBDT and random forest, how to determine the k value during k-means cluster analysis, and how to determine when performing index dimensionality reduction in my small thesis My own dimensionality reduction, at that moment, I just wanted to be bad, I can only say that I really didn't study hard, but it was too late.
And actually this time, I was well prepared. I went to Niuke.com to do some questions, and went to see other people’s face-to-face scriptures. I was obviously investigating linked lists, reversing linked lists, etc. I forgot the rest, just It is still not solid enough to study by myself, and failed to meet the requirements of the work.
Then, in the questioning part of the interview, I didn’t know what to ask, so I could turn the tide and tell the interviewer that I really wanted to go. I think my learning ability is okay, but I can’t tell you how hard I worked when I was studying. , At that moment, I felt that I had resigned to my fate, if I don’t want it, I don’t want it. - Didi Data Operations Intern 2022-8-26
The interviewer is very nice. He will talk to you about the competitions on your resume, such as the mathematical modeling competition I participated in. He will let me talk about the models built in it in detail. How to solve the problem, and communicated with the interviewer about the specific responsibilities of this position. Since I am biased towards the operation position, I will use tableau software, and most of the content is to analyze data and make report presentations. It is recommended to read some books of product managers. - Huo Lala Data Mining Intern 2022-9-1
There are two rounds of interviews, I passed the first round, confused, I am very happy, the interviewer is very nice, most of the time he is talking, and I also believe it Me, because I directly said my mastery of each language, he trusted my ability, and mainly talked about the specific responsibilities of this position.
In the second round of interviews, the interviewer was a product manager. I think it was a Fermi question, asking me to estimate the number of taxi orders in a city. I felt that my thinking at that time was still not divergent enough, as if a problem was given to me, and I went directly to solve the problem without thinking. - The interviewer for the Kuainiu Intelligent Data Analysis position
is very strong in machine learning. Whether it is supervised learning or unsupervised learning, he has a strong grasp. Under his questioning, I obviously feel that my learning in school is still too shallow , use the simplest method to solve a simple problem, and then let me realize again that the previous life paddling will have retribution. Just the day before the interview, I was still thinking about how this company is. Today I feel that I am not worthy, and I am also regretting it. I think that if I have the opportunity, I should be able to learn a lot from it.
During this period of internship, I think the questions asked in the interview are quite difficult. I feel that I need to be really prepared and study fully.
In this experience of looking for an internship, I submitted a lot of resumes, few companies responded, and even fewer companies gave me interview opportunities. I think I have not submitted resumes recently. I am very worried that I will soon finish my investment in companies, and I will not have interview opportunities with these companies in the future. I also think that the company should be busy with autumn recruitment recently, and it is quite difficult to find daily internships.
In addition, I really want to ask, when these companies can deliver the second time, tell them that I have grown up, and give me another chance for an interview. After all, Shibie looked at each other with admiration for three days, hahahahahahaha.
At least this time, I know, to take everything seriously, take them seriously, prepare in advance, plan well, and it is best to ask others for their experience.
