I rarely talk about my interview, but today I talk about my interview.

You still remember a month ago I said that I would go to experience the interview factory, find out where the gap is, but also let yourself learn what the mainstream technology now, whether I do not comprehensive enough, don’t be eliminated.

Yes, I did go to (byte) and summarized the exam questions after going there. Recently, I have been updating some interview questions, but I haven’t shared my experience, so I will talk about it today.

01

Why are you interviewing big companies

As mentioned above, I mainly want to see if my current technology is mainstream and what is lacking. I also want to see what big companies are using and where I am lacking.

In times of peace. Learn more about your shortcomings and make them up as soon as possible.

The most important thing is to see if you can find a new job. (It is also the latest epidemic news, what unemployment, difficult to find a job)

02

Preparation for an interview

Before the interview, I made full preparation. I looked for all the interview materials I could find in bytes. I looked at them in general and also looked at many algorithms.

Also collated their own ☞Java basic knowledge topic, or a good look again.

And the development of their own projects, highlights and main functions are fully reflected in the resume, I explained to myself many times in the bottom of my heart.

I also gave a good description of my work priorities, highlighting my performance, abilities and results.

I also learned about the current mainstream technologies and frameworks in the industry, including some good open source projects and open source use.

It feels perfect to be who you are.

I made the appointment half an hour early on the day of the interview, which is my usual style, always afraid of being late.

In the interview, there are two people, two people are from different fields, one is used in the project, the other is basic.

Of course, the first thing is to make an introduction. I briefly introduced myself and then began to extend the project. I only took 1 minute to present the project well.

At this point one of the interviewers asked me a strong quote, a weak quote, a soft quote.

This is certainly not difficult for me, before the interview special research memory leaks, which has ways to prevent and detect leaks, which has weak references.

▌ Java strong reference, weak reference, soft reference, how to do?

The problem is certainly easy to resolve.

After that, I asked another question about the caching methods used in some projects. In this case, I mentioned the background storage and front-end caching mechanisms commonly used by us, as well as some advantages and disadvantages.

After that, the two people switched back and forth, but I found that they mainly had more requirements for basic applications, and most of the things developed in the project were also related to the project I did.

For example, some considerations of the project, the design of some scenes, the technical considerations of development and so on.

The most regrettable thing was that they gave me a concept of their scene, and MY answer was pretty bumbling.

I feel that some of dachang’s considerations are deeper, and the difficulties they face are more difficult and refined. At the same time, SOME of their scenes are unknown to me.

conclusion

It is said that it is difficult to interview in big factories, but it is also related to the environment and vision we contact. If we stay in a start-up enterprise for a long time, we will also work in some small and medium-sized enterprises, so we only consider this range.

But dachang is beyond us.

The talent of big factory is more refined, each of them is a point, many people constitute a surface.

Small factories often have only a few people in total, requiring more and more extensive technology, and even now require to make a full stack, without them, it is more professional and more detailed.

Well, these are some of my experiences and feelings, and I will summarize these technical points for you later.
