Preguntas de entrevista para Isaac Operations

This is regarding the first step which was the prerecorded video interview: Was 5 questions. For 4 of them I think it was like 1 min prep and 3 mins to answer. From what I remember some of the ones I got were: - Tell me about something that's not in your resume - What was your greatest achievement, what did it take to be successful - Some group project/experience type of question Honestly forget about the first 4 they were typical interview questions if you do any type of interview prep you can put together a decent answer for them. Now the last one was a math word problem. It's not hard but I just didn't expect a math question at all so it caught me off guard and I fumbled. I had 3 mins prep and 4 mins to answer for that one I think. Below is an example of the question from what I remember so you have an idea of what to expect: There is a Cupcake Factory, in that factory there are: 8 hours shifts, 3 shifts/day 7 days a week, 50 weeks/year 50,000 packages produced per shift Cost of labour is $20/hour Waste is 4 bins per day Each bin can carry 50kg Cost of goods is 50 cents per kg It takes 10 minutes to pack waste Waste is packed 3 times per shift Out of 30 people 6 people pack waste during downtime Question is, is it worth it to pack waste, why or why not? I wouldn't try to solve what I wrote, it's just a general idea from what I remember the numbers are probably wrong, but the process is still the same. You then have to explain what your thought process was for solving it and defend your answer. Like for the question I highlighted, my mistake was I started calculating random things like how many shifts and hours of labor there are in a year. When I should've focused on calculating the labour and opportunity cost of packing waste versus keeping workers focused on cupcake production, and then determining whether the value generated from continued production outweighed the cost of handling the waste. I might be wrong about that, but either way don't get lost in the numbers, just determine the relevant variables, calculate what's needed to get them, and then explain your answer. It's basically just a middle school math word problem.

The entire recruitment process was direct and to the point. There are 3 tests after your application that encompass analytical, personal, and mathematical aptitude. All three are not too difficult. The next step is a virtual interview where you are asked personality based questions. The recruiters are fantastic and get back to you personally.
