I was treated pretty poorly throughout the interview process. Twice I showed up to the initial Teams Meeting, stayed on for 45 minutes, and no one else entered the meeting. The interviewer then told me they were on - but if this was the case, why didn't they just call my phone and ask where I was? I eventually talked to the interviewer and had a poor experience. Ended up abandoning seeking the position because of this.

So hard, need to learn more on technical question (very basic) such as what is airflow, explain chiller, what is air flow rate. But, the interviewer give good feedback and comments.
