Job Interview Questions
Creating a Map of the U.S. Showing Customer Locations/Concentrations
Recommended Tool: Tableau
- Tableau is a powerful data visualization tool that excels at creating geographic heatmaps.
- It can process customer location data and represent it visually on a map.
- It integrates well with databases and spreadsheets, making it easy to import customer data.
Keeping Track of People Who Called and Whether They Became Customers
Recommended Tool: CRM (Customer Relationship Management System)
- A CRM is designed specifically for tracking customer interactions, including calls, emails, and follow-ups.
- It allows the company to log whether a person becomes a customer and track their journey.
- Many CRMs offer automation, reporting, and reminders for follow-ups, improving customer relationship management.
Tracking Contracts Issued Over the Past Year and Categorizing Them
Recommended Tool: Excel
- Excel is an excellent choice for tracking structured data like contracts over time.
- It allows for easy filtering, sorting, and categorization of contracts.
- With pivot tables, the company can quickly generate reports on how many contracts were issued per month and their categories.
Analyzing Focus Group Data for Customer Preferences
Recommended Tool: MaxQDA
- MaxQDA is a qualitative data analysis tool designed for processing focus group data, interview transcripts, and open-ended survey responses.
- It allows for coding, thematic analysis, and visual representation of trends in customer preferences.
- It is more suited for qualitative data compared to other options like Excel or Tableau.
Search Engine Comparison
1. Search Engines Compared
Google vs. DuckDuckGo
2. Lexically Ambiguous Searches (e.g., “China” or “Washington”)
- Google: Provides a mix of results (country, politics, tourism, news) with clustering. Related topics appear as sections or “People also ask” suggestions.
- DuckDuckGo: Offers a broader mix but with fewer personalized results. Wikipedia entries and neutral sources appear first, with less clustering.
- Better Handling? Google, due to better clustering and intent-based ranking.
3. Minimally Ambiguous Search (e.g., “Langfun Tech Office Manager Job Posting”)
- Google: Prioritizes job postings with structured data, making the results highly relevant.
- DuckDuckGo: Returns a mix of company pages and general job-related articles.
- Better Precision? Google, since it ranks official job listings higher and filters out unrelated content.
4. Determining Recall
- Recall is difficult to measure since search engines don’t disclose their entire indexed database.
- Why? We lack a complete list of all possible relevant results to compare against what’s retrieved.
- Conclusion: Precision can be compared, but recall cannot be definitively measured.
