Should I use "is" or "was" in the below sentence?

Shirley was the second person whom I interviewed at 24 Hour Fitness.

Since this action took place in the past, use "was."

To determine whether to use "is" or "was" in the sentence, we need to consider the tense of the verb and the context of the sentence.

In this case, the sentence talks about an event that happened in the past - the interview. Therefore, it would be appropriate to use the past tense verb "was" to match the time frame of the interview.

So the correct sentence would be:

"Shirley was the second person whom I interviewed at 24 Hour Fitness."
