Inspired by the "Why YOU Aren't Getting Offers" repost for #TBT.
I just participated in a series of interviews and I was sincerely disappointed. I was asked to cover the technical portion and no one could walk me through a DCF well. While I am going to talk to the people who referred these candidates (and also make note of the quality of their referrals), it occurred to me that often candidates don't realize or get clear feedback on why they didn't move on in the process (interviewer has no upside, potential legal nightmare, against policy etc.). Yes, there are always "better candidates", but there are some very common (and highly fixable) problems I see way too frequently. Perhaps that's the frustrating part, because I feel like these are things that are very easy to prepare for.
It's not just about getting it right, but presenting it well.
Let's use an example of DCF because it is standard / plain vanilla / middle of the fairway. You will get this question for sure at some point. You should know this cold. It should be polished. There is no "but what if I sound too canned" debate. I have never heard anyone sound "too canned" on something like this (or anything for that matter). I HAVE dinged people for just regurgitating when it is clear they don't really understand what's happening.
