Once I was told to interview a junior dev. It was my first ever interview from the side of employer, so I hope this story will never appear here told by my vis a vis. Ok, to the subject. Position of jun iOS dev. It was so long time ago, the manual reference counting was the only option on a platform. And I ask her, to describe how the manual ref counting actually working. She cannot answer this. I try to split the theme in to a pieces and ask more precise questions, about this or that situation, what should happen, or at least how she thinks it may work. She cannot answer this as well. Technically for me it was the end of interview, but I cannot give up on her that easy so I ask her to tell me what she is doing on her current position and we had spoke for another 15 min. TLDR she has failed.
Next year, another company, interview for the same position, the same people on the scene. So, I remember her, she remembers me. We both know the question I will ask. TLDR she has failed on the very same question.
Oh god knows how bad I feel after rejecting her second time. But I was little more experienced with the interviews and I was sure this question should not be a problem to those who have little experience on a platform.
Several years has passed. Another company. I’m about to jump to the next company and project managers are doing their best to fill the position with ANYONE as it’s a big fight for developers at the moment. So they have found a junior inside the company who wants to try. And SAME PEOPLE on the scene. Same question on a table. And some other questions, and more. So she’s got that job.
After many years I can say she could have a job from the first time if only I try to question her about other sides of day to day code writing. It was just me - not very experienced interviewer and not very experienced mid developer. I only hope she is not hating me a lot.
