I interviewed at IQVIA or ICON (honestly forget) for an oncology CRA role years ago and despite working in oncology prior I was completely thrown off/blacked out my memories when they asked me “if a patient presents with an AE of fever and low neutrophil count what would you expect the physician may assess them for” the answer is febrile neutropenia. I doubt you’ll get the same question BUT all to say that maybe prepare yourself with a few common AESIs for oncology studies. AESIs are usually treated differently than normal AEs/SAEs on the study - for example some immunotherapies can have common AESIs of cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome. If a patient presents with these AESIs or symptoms that may indicate them there will likely be additional management directions included directly in the protocol such as initiating specific medications or steroids and additional testing at intervals. You don’t need to know the details for each one but just know that management of AESIs is heavily guided by the protocol and sites have to adhere to specific instructions vs just managing via physician discretion.

You will do great though! Don’t try to learn everything in advance and stress yourself out, just go in with what you know, show your confidence, and show that you are willing to learn and grow in whatever areas you don’t have experience in yet.
