Product Interview Questions

I didn't have a good answer for this one.

Its such a tricky question. I guess its by the analytic we use to know the page views and all..

Try to define "scale", ask for clarifications. Are we trying to scale to more users or to more ad providers? Are there any current bottlenecks? What is the goal here? How about we improve the experience by providing more relevant ads? etc...

This is a test to see how you think on your feet.

Adword Revenue : No. of impressions * Click Thru Rate * Cost Per Click Anyone of the three parameters could decline to have an overall reduction in revenue. No. of Impressions could go down if a. The internet usage has fallen for some socio-culturaal reasons in Italy b. The usage of Google search has reduced because of may be some competitor applicaton launch or some major marketing promotion activities c. Some major technical issues has come up may be in the Google servers which is resulting in higher latency in Google Search applications resulting in reduced usage Click Thru Rate might have gone down 1 Major shift is usage clusters Keywords used have changed resulting in changed search behavior where in people are less prone to click thru. 2 Some technical issues like adds not displayed properly Same major flaw in random add picking might have got introduced 3. Some recent layout change has been there and peope are yet to get accustomed with the changed layout Reduced CPC: 1. People are spending less on Adwords and hence bidding less 2 Due to the keyword change, the new cluster CPC is much lesser.

1. Determine the amount of decrease in month over month percentages, and make sure this isn't a trend. 2. Assuming we've seen similar decreases in conversions and clicks, 30 days is a month's time. Let's say this is in August, when the entire country uses the majority of their average of 42 vacation days per year. That's a factor. 3. Given you've said decreases in revenue and assuming all click and conversion data remained the same month over month, we may look for broken dynamic revenue variable conversion codes on the page source. Was there a site update?

Before I would stop a line I would make sure that I had evidence which I could use to justfy the stop. If this evidence was insufficient to stop the line or if the decision by the policy holders was not to stop the line but I felt that the problem was important enough to the customer I would escalate the problem to the Director of Quality. Unfortunately I could provide no examples that actually showed me being effective because they were all company confidential. The minor issues I could describe were not very impressive

Reduce the length, increase the thickness, change the material to one with a stronger young's modulus (just have to be careful about the tradeoff between material density and stiffness).

Taper it.

The answer they were looking for was that the legacy product should be offerred tothe price sensitive customers, while migrating other customers to the more expensive, advanced newer product.

I would put together a launch plan with input from the necessary teams: Product Management, Engineering, Testing, Support. A part of the plan would include schedule, key stakeholders and responsible team members, and key deliverables and milestones with dates. I would arrange weekly meetings leading up to the launch date and manage the progress on each of the milestones and deliverables by coordinating with each of the team members.

Good indication of behaviors that are common in this organization. No job is worth total humiliation.

I would definetly keep my cool and act very professional and say... I understand your concerns. Please send me your issues in an email and I will make sure I set up a conference call so we can discuss them in further detail.
