We have lost all data for Google Maps' street view in New York. What would be the cost to restore the street view?

This question primarily involves estimation and is designed to evaluate your problem-solving abilities, creativity, and understanding of the economics and operations of a tech company such as Google. The interviewer is asking you to estimate the expenses involved in replacing all the street view data for Google Maps in New York. This entails calculating the costs associated with data collection, necessary data processing, and related labor expenses. Consider how Google gathers street view data (through specially equipped vehicles that travel around capturing 360-degree images), who participates in this process (such as drivers, data analysts, developers, etc.), and how long the entire operation might take. Keep in mind that there is no single correct answer. The objective of the question is to assess the clarity and transparency of your reasoning. Important aspects to consider: Expenses related to data collection (condition of the fleet, vehicle costs, cameras, fuel) Labor costs (drivers, data analysts, software developers) Estimated time required to replace the lost data.

To update all street view data in New York, we would essentially need to replicate the original data collection process. Here’s a breakdown of the costs involved: Google collects street view data using vehicles equipped with camera systems. Assuming we need 10 such vehicles to cover all of New York, each costing approximately $200,000 including necessary equipment, our initial investment would total $2,000,000. These vehicles will require drivers. If we pay each driver $20 per hour for an 8-hour workday, five days a week, the total weekly wage for all ten drivers would amount to $8,000. If this operation takes around 6 months, or about 26 weeks, the overall cost for driver wages would reach $208,000. Next, we have fuel expenses. Assuming each vehicle travels about 100 miles daily, five days a week for 26 weeks, with a fuel efficiency of 10 miles per gallon and an average gas price in New York of $3, the total fuel cost would be approximately $390,000. Lastly, the collected data must be processed and integrated into Google Maps. If a team consisting of five data analysts and five software developers works on this for 6 months, with an average salary of $100,000 per year for each, the cost would amount to $500,000. Summing these expenses, the estimated total cost to replace all street view data for Google Maps in New York would be around $3.1 million.

Estimating the expenses involved in replacing Google Maps Street View data for New York requires an assessment of multiple factors. The primary cost elements include data collection, data processing, and labor. Google gathers street view data using vehicles outfitted with specialized camera equipment, so we must include expenses for these vehicles, their upkeep, fuel, and the drivers who will operate them. After the raw data is collected, it is processed by teams of software engineers and data analysts. Next, we need to estimate the duration required to gather and process all the data. Assuming it would take approximately six months for data collection and processing, followed by another six months for refinement and enhancements, we can expect a total timeframe of about one year. If we allocate $500,000 for equipment and data collection, estimate an additional $400,000 for data processing and software development, and include the salaries for the drivers, software engineers, and data analysts over the year, the overall cost could approach $2 million. Keep in mind that this is a rough estimate. The actual expenses may fluctuate based on various factors and circumstances that may not have been considered. I suggest conducting a thorough study for a more precise estimation.
