Android-Wuhan baina information (dolphin browser) Android interview Summary

1. Recently, due to some reasons, I was a little disappointed with the current company, so I was impulsive and had the urge to go back to Wuhan, so when I saw the Wuhan baina information, that is, the Android development recruitment information of the dolphin browser, I contacted the other party and got the opportunity for this interview. In front of the technology, I have had a phone call with their hr staff for more than an hour. In general, it gives people the feeling that their interview is not that easy, their requirements are still quite high. At least in an hour of hr communication, this information was obtained. As a result, we had an appointment for an interview at noon today. At one o'clock, the interview started on time and took a total of 40 minutes. As the saying goes, there is progress only when there is a summary. Every interview is a good opportunity to summarize. So, let's make a summary here.


2. Specific interview knowledge points.

In general, the research is still comprehensive and in-depth. Some basic knowledge about the lifecycle, screen adaptation, and layout of the activity is not involved, but the basics of java are as follows, the multi-thread, service, and design pattern are much investigated. Let's talk about the specific knowledge points and give the children's shoes as needed.
