I am a software engineer and a fresh graduate from college, so after my graduation trip I start applying to pretty much every job in the area. I heard back from three company's let's call them company A, B, and C.
So today company A calls me back after my first in person interview and tries to schedule an interview, but I already had an interview scheduled with company B. Thinking I had to provide an excuse to company A I told them that unfortunately I had another interview planned that day while trying to still sound very interested. I know company A wants to hire me but location and job isn't as favorable as company B. One is more support than development and I want to be in development.
When I told my dad I had told them about another interview he told me it was a major mistake. I provided them absolutely no details on the other interview apart from the scheduling conflict. I was wondering how much harm people think I did my mentioning the other interview?
Also company B is a much larger company so I know their process takes much longer. I Was wondering how much time people thought I could potentially delay company A if they do give me an offer. I did schedule an interview with company A at a new time. I know this my final interview at both. Thanks in advance for other peoples insight.
