Nothing out of the usual path. Background review Business Case question (assumptions, structuring) no math included. If a GSM operator would like to make a decision about investing into a new market, what are the major criteria?
Agreeing to a little less salary offer was a bit difficult for me but the HR head successfully persuaded me to accept the offer by realizing me the opportunities for professional and career growth at this company.
Simple case. Use the market, customer, competition approach. What we would do is..... create business cases and cost models based on different scenarios, e.g. FttH, FttC, etc. But I couldn't relate to the interviewer. He seemed rather arrogant and when he said that my current company was not in the same league, I lost whatever remaining interest I had. He definitely did not represent Delta well. And we're in Consulting?! LOL! It then changed a bit, I was then asked about what I would say to the CEO if I had 10 mins. Simple. Go for it! Use your copper network to provide differentiated or tiered services to residential and corporate/enterprise customers (note the segmenting). If you understand virtual unbundling, you can offer services to other players (assume competitive market) and/or wholesale (many ways to do this) to the mobile guys even. Anyway, this was a bad interview with a bad interviewer.
A simple case really. Take Netflix as an example. They want to enter a new market, say the UK. Estimate the market size and success factors. Monthly subscription is €7 a month and VoD is € a movie. As with any consulting case, always segment! Segment your customers (e.g. high users, mid users and low users). But make it interactive/conversational - include the interviewer (I didn't really do this).
