An exploratory round interview was scheduled by an HR from Careernet, to be taken by a senior engineering leader. The interview was rescheduled TWICE without any prior intimation. The interviewer did not join the meeting link. I've had to move around my schedule completely to accomodate the interview, but the unprofessionalism around it left a sour aftertaste. Regardless, the interview did proceed to happen the third time. However, there was very little exploration on data science skillsets. Instead, the interviewer provided a problem around designing a pipeline, and a bunch of open ended questions (for example, how will you use an LLM here?). The objective of the exercise was not clearly laid out. It felt like it was an analytics/data engineering question. The interviewer ask for my notes (i had structured my solution in an excel sheet), and then there were closing questions. Two days later, I got a rejection email. All in all, pretty disappointing experience. This coming from such a large tech firm like Microsoft was unexpected and left an indelible mark in me.
