I recently had an interview with a large firm for a software engineer role. The interview was organized through a recruitment agency.
The night before the interview the recruitment agent sent me an email outlining what format the interview will most likely take and what kinds of questions in which areas I can expect (including which technical areas). At the time I didn't think much of it as it was more or less what I could have guessed anyway.
After the interview when I spoke to the agent she began asking me some detailed questions about the interview. She wanted to know what kind of technical questions they asked and other things. In my head alarm bells went off and I gave her vague answers.
I am suspecting if I had given her more information she would have passed this on to her next candidate she was sending to this company which would have done two things: reduce the likelihood I would get the job by giving the next candidate more detailed information and a chance to prepare better - and increase the likelihood she would land someone the job (potentially benefiting her company and possibly her if they work on a commission basis).
I have never come across anyone who sent me an email with detailed information about what to expect during the interview and then afterwards ask what was asked in mine.
Is this a new trend in recruitment or is she a rogue recruiter?
Is it ethical considering it isn't fair if you're one of the previous candidates and considering the employer isn't getting the best candidate?
If it is a trend then what would be the best way to deal with someone like this if it happens again?
tl;dr Recruiter asking what was said in interview to help next candidate. Is this acceptable, whats the best way to deal with it?
