Alot of interviewers do not know how to conduct interview as well.

Straight up asking textbook question and expecting non-textbook answers?

Like asking shit question like weakness/strength/aspiration/motivation. What motivates you? The answer is always money (most sincere non bullshit answer).

Many still kinda confused

1. I start my interview on a short intro. I intro myself and my company then I ask interviewee to intro and what they do.

2. Based on what they do I generally know what's their knowledge and skills level at (I am their reporting manager if hired). For me my concern is that are you able to do the job youre expected to and can I work with you.

3. If there is any confusion, I will ask in details like what they do. e.g. the candidate told me he work from scratch a project with other dept and lead to increase in 30%. Then I ask what is the project - he cant answer me instead he give me example, i bring him back and rephrase my question, "you mentioned earlier you work with other dept on this project that lead to increase in 30%" what is the project about and what 30% increase? what metrics? He cant answer me, instead he give me more example of the things he do which if listen carefully is rather vague

4. Graduated on the year 2021 (presumedly graduation on year end) now working as AM? either he is super capable or something is wrong.
