Snapshot
Snapshot is a new tool from the CASPer team. It is a mini-interview, during which you are recorded the entire time. It consists of three questions, each of two minutes’ duration (i.e. you have two minutes in total to read the question and give your answer to it). You are able to practice before you sit the Snapshot part of the test, using the practice questions. Note that you will be recorded while you read the prompt. You should not expect the Snapshot to take more than 5-10 minutes at most – however, you can take a break between questions if you desire. BlackStone would advise not taking breaks between questions, as in an interview this short you are likely to perform better if you remain concentrated and on-course throughout.
Duet
 The Duet component has no time limit. It is built to compare how your values compare with those of the institution that you are applying to. As of 2021, it is in use only by residency programs, as part of CASPer’s GME (Graduate Medical Education) Suite. You will compare 30 program characteristics in pairs, over three categories. CASPer implies that you ought to complete the test relatively fast, stating that you should use ‘gut instinct.’ We would advise against this approach, and caution instead that you are more likely to succeed if you approach the test slowly, and give great thought to which characteristics are likely to be most valued by the program. If you spend time on positioning yourself in a similar way to the program, you are likely to perform better than if you give rushed ‘honest’ answers.
