This is, in my personal experience, a sad truth.
I've been seriously looking for work for the past 6 months (thank you, Covid-19, for your disruption) and I'm surprised by the number of times I've started a phone interview with questions like: "tell me about your skills" ... has the interviewer not looked at my CV with its link to GitHub and various live projects I've done?
Yes I know engineers and interviewers are busy people with real jobs and deadlines and stuff. But I've been on that side of the table too. I've conducted plenty of interviews, online and face-to-face. Not researching the candidate before you talk to them or meet them ... that's just discourteous (in my view). Even 15 mins spent checking out the links they've supplied can give the interviewer a feel for the candidate's potential strengths and weaknesses and help the interviewer personalise the "standard" questions to better fit the candidates experiences.
Interviewing is an unpleasant task for everyone. Making the experience even a little less unpleasant can help everyone make better hiring choices at the end of the day.
