Android used to be the No.1 programming language. People who choose to enter the IT industry and do programming and development basically regard it as the language of choice. Stephanie Cuthbertson, senior director of Android, said that there are more than 5.5 billion
devices running this operating system worldwide. , which is still less than 10 years after the first public release of Android.
Android is used in many world-renowned companies, including foreign eBay, linkedin, Amazon, Facebook, etc.; domestic Ali, Meituan, JD.com, etc.
However, as the number of people engaged in this industry gradually increases, the competition in the industry is also increasing. The recruiting companies and programmers want to recruit the talents they need/find their ideal positions; making Android interviews more and more difficult now, Inward scrolling has long been the general trend, and everything can be rolled, and we are no strangers to curling up. Many times, we want to lie flat and become a flat-laying family (manual dog head).
All jokes are jokes, life has to go on, who doesn't work hard secretly while complaining. Maybe when you were a salted fish, your colleagues were already preparing for the interview, and won your ideal offer before you knew it! No, recently there have been private messages from fans in the background asking me if there are any interview notes that are full of tears. Now interview questions, interview books, interview manuals... There are a lot of interview questions, and I can't read them all, and I can't read them. Come on, every time the favorites are dusted, I want to really brush up the interview summary with high gold content.
In my spare time, I am sorting out an interview manual. First, let myself review it, and second, I hope to help more colleagues. It's not finished yet, but it's almost there! I will share it today, hoping to help everyone in future interviews! (Not much bb, let’s look at the main content)
