About the interview question

For example , If you understand looking for a job as going to college , The interview is the college entrance examination , On the market “ The real question ” It's a mock test paper . It's easy for us to look for an interview with the corresponding company before the interview “ The real question ”, Focus on preparation , expect “ predict the content of an exam ” success . But actually , Even if you interview the same company , It will have different departments , Different lines of business , Different interviewers , Even if you meet the same interviewer , He doesn't have to examine exactly the same content every time . Think about those students who did well in the college entrance examination , They certainly don't rely on “ predict the content of an exam ” To get good grades , Most of them rely on ordinary accumulation and flexible mastery of knowledge points , So is the interview . Persistent in searching questions , Take the interview questions as the focus “ review ”, You might as well draw out “ Examination outline ”, Check the mastery of each knowledge point one by one , More comprehensive review .

My opinion on the interview questions has always been relatively conservative , Such articles are generally just content handling , There will be some deviations and Misreading , The most important thing is to throw a few questions at that one , Didn't produce anything of value . That's why my last interview summary , Will add some interview skills , When sorting out interview questions , I didn't mention which company they came from , I just don't want you to treat the subject differently .

This is not to say that the face-to-face test questions are useless , But I hope you don't believe in interview questions , Pay more attention to those technical articles with quality and depth . The interview assesses knowledge points rather than specific topics , The function of interview questions is , Measure our mastery of knowledge , It is convenient for us to find out and fill the vacancy , The more you say it, the more it seems to be directed at one time “ The test ” 了 .
