As tech leads, Jack and Sally would wear a lot of hats: writing codes, testing, writing stories, meeting with clients, coaching, reviewing resumes and interviewing candidates, and more. As consultants, sometimes they would even be hired by a company specifically to help build a team through hiring, training, and mentoring.
As coworkers, Jack and Sally would often work together at the same client, even if they were performing different functions. But they always touched base on candidates, requirements, and decisions that warranted extra input.
So when Sally's client asked her to interview three different candidates for a development position it wasn't unusual that she asked Jack to join her in the interviews to get a second opinion on each of the candidates.
For each video chat interview she joined first, introduced herself as the tech lead, then brought Jack in and introduced him as a Sr Developer that would be helping with the interview. She and Jack took turns with questions, but she opened and closed each interview.
The first two interviews went well, Jack and Sally wrote up notes and prepared them for the client, but waited until all of the interviews were complete to issue a recommendation.
The third interview started much the same way, and after making introductions Sally asked the candidate the first question. He responded with, "Jack, here's what I think ..." and continued with his answer. Sally and Jack glanced at each other, but continued with the interview. Jack asked a question and the candidate responded. Then Sally asked a question and once again he responded "Okay Jack," before answering the question.
This proceeded the entire interview with the candidate only addressing Jack, despite the fact that Sally had told him at the beginning that she was the interviewer and would also be the person the new developer would report to.
Needless to say, that third developer didn't get the job. It was one of the worst cases of self-sabotaging sexism they had ever seen in an interview.
