I have been apart of a fair amount of interviews within my time searching for a career that best suited me. The most effective interview I sat in was my last interview, where I received the offer for my current job. Since then, I actually have conducted several interviews over the course of my career, and have learned many valuable lessons along the way.
Interviews are extremely valuable tools that help managers evaluate potential qualified canidates, and find out more about their strengths and weakness. When used effectively, it can produce a valuable outcome such as finding the best fit for the team. Reflecting on my own experiences, the most effective interviews were the ones that felt structured, consistent, and directly tied to the job description. These types of effective interviews asked questions like “Tell me about a time” and evaluated responses using clear criteria. Considering my own interviews I’ve conducted, we use a grading system while identifying the answer we’re looking for as a team. This improved reliability, because each candidate was assessed in a similar way, and validity, because the questions were clearly related to the attributes required for the role.
The most ineffective, and actually worst interview I’ve ever been apart of was a very informal, and unstructured one. I applied for a landscape position. I met the owner at a project where he showed me informally what they do, and the interview ended by him stating “It’s not a good idea to steal from me”, which felt very threatening. Needless to say I didn’t accept the job offer. This style of informal interviewing, and giving personal remarks based on ones experience or opinions reduced the reliability of the interview, and took away my desire to work for the company. “But while unstructured interviews consistently receive the highest ratings for perceived effectiveness from hiring managers, dozens of studies have found them to be among the worst predictors of actual on-the-job performance — far less reliable than general mental ability tests, aptitude tests, or personality test”(Iris Bohnet, 2016).
I am an extremely hard worker, and would’ve been a great asset to the company. By having an unstructured process, he lost out on a great potential employee.
If I could give advice to managers, I would recommend implementing structured interviews with standardized questions and scoring systems that reflect the job description. Another important factor would be training interviewers to recognize bias and focus on job related competencies would that also would improve outcomes.
