Interview: You must be a professional speaker. You must check the nature of your questions.

I have been interviewed by several software engineers over the past two days.

I asked a question:
What is the difference between Oracle database and MSSQL data?

Basically, I have selected people with more than two years of experience for interviews.

The answer is mostly similar: mongoel is a database used by large projects, and MSSQL is usually used for small data storage; Oracle Security level is high, MSSQL security level is lower .....

Although this question is very simple, I think the answers to different people or people at different levels are different.

I would like to say that I am not here to recruit database sales personnel. If you can see the saliva in any market, you will be free of it.

As a "professional" software engineer, if I look at this problem just like this, I think it is completely impossible to see the nature of the problem and completely unprofessional mentality and knowledge structure.

Are the two databases different?
Database instance comparison?
Why is the Oracle Security Level High? It is because of what standards Oracle implements...
Which standard Does Oracle PL/SQL implement for SQL, And what standard does MSSQL implement?
What is the comparison between sql2005 and Oracle 10 Gb? List New Features of sql2005?
Oracle provides more complex data types. Does MSSQL correspond to one another ..?
....

As mentioned above, I think it is a matter of concern to software developers. It is a big and extensive discussion of superficial things. It is a rejection of the profession and it is also irresponsible to myself.
