Stupid question asked in interview.

I was recently called for an interview, and the interviewer asked me a puzzle. It goes something like this: "You have two containers, C1 and C2, both filled with equal volumes of oil and water, respectively (i.e., C1 -> oil volume V and C2 -> water volume V). A spoonful of liquid is taken from C1 and poured into C2, then a spoonful of liquid is taken from C2 and poured into C1. After these two steps take place, which container will have higher purity (concentration of oil for C1 and that of water for C2)?" I thought for a while and answered C1, citing that since we put pure oil from C1 into C2 but a mix from C2 into C1, certainly some oil from C2 is back in C1, thereby achieving more purity. The interviewer said it was wrong and asked me to try again. This time, I did some actual math and was told C2 would have a greater concentration based on the calculations. The interviewer again tagged me wrong, so I asked the interviewer to explain, and his answer was that both would be equal since you take 1 spoon of oil from C1 to C2, and put 1 spoon of water from C2 to C1. This is obviously flawed, as no oil is getting back on the spoon when you dip it into C2. I wanted to point that out but didn't. Later, I re-did my math thoroughly and found that C2 would have a greater purity of water.

Having some fun with the interviewers

So basically I don't hesitate in challenging the interviewer if I feel like they don't know how to interview a senior candidate so during many interviews, this is how I have caught them off guard: 1. The interviewer was asking me technical questions and expecting to explain properly throughout. So at the end i asked him about the tech stack they use, he said Azure. I asked him why they use Azure and not AWS, to which he said "it's cheaper", i didn't let it go, i asked him for a proper technical explanation, his red face was worth seeing. 2. The interview asked me a hard DSA question, and I wasn't able to solve it properly, he didn't even give me enough hints, just expected me to solve it. So halfway I asked him, would you like to solve a DSA if I ask you right now, he said no because it's not his interview. To which I asked, are you afraid that you won't be able to solve? If you are going to reject me for not solving this question, would you resign if you aren't able to solve the question. He ended the call. 3. One interviewer was asking me absurd technical detailed questions. I asked him why are you asking such questions, he said he needs to know my thought process because he will work with me. I started asking him similar questions, he said he won't answer because it's not his interview. I said I also need to know your thought process because we'll work together, so you should also answer these questions, he had no reply. 4. The interviewer asked me about a challenging project that I had done recently. I don't like this question at all. So I said there wasn't any challenging project because I'm good at what I do so it's always easy for me. He moved on to the next question. 5. HR asked me why I resigned without an offer? I asked if it's mandatory? No reply.

ServiceNow interview is shit 💩

I just finished an interview with ServiceNow for a senior software engineer role and writing this up. Anger rushed through my body after finishing the interview for multiple reasons. reasons: 1. The interviewer joined 10 minutes late and he was very lethargic. 2. The questions he asked regarding my current job were very basic and then I realized that he should be fresher or should have 2 - 3 years of experience. 3. After the interview I checked his profile on LinkedIn and he was a 2021 graduate (as I guessed). 4. I don't understand why an organization assigns software engineers (2.5 YOE) as interviewers for hiring a senior software engineer(8+ YOE). It doesn't make sense to me. 5. Then the interviewer asked a basic DSA question, and I gave him the solution, now he was not familiar with the Python language hence intrigued about the implementation of the heapify in Python. I explained to him how Heapify works but still, he could not understand what it is. 6. The part I got pissed off is the interviewer's attitude of him knowing everything. 7. The interview was scheduled for 1 hour and we went overtime, it's okay to go overtime by 5-10 minutes., But this guy is taking more than 20 minutes. He din't have basic ethics of valuing candidate's time. This is not my first interview with ServiceNow, this is my second and I had same feelings in the first interview as well. It's okay for me to not grab this opportunity, but think about someone who is really struggling to get a job during this tough time, because of the interviewer being lethargic. Hope ServiceNow focuses on their interviewing system and improves it.
