Tech Consulting Case Interview: Complete Guide (2026)

Main summary

Key takeaways

Educational

Main ideas, concepts, and lessons

  • Technology consulting case interviews (e.g., Accenture, Cognizant, “Deote”) test different skills than traditional strategy consulting cases.
  • Common failure mode (~80% of candidates): treating tech cases like traditional strategy cases and only adding tech terms.

What’s different in tech cases

  1. Focus areas

    • Traditional: market dynamics, competitive positioning, profitability drivers
    • Technology: systems architecture, implementation feasibility, digital transformation

  2. Key metrics tracked

    • Traditional: revenue growth, market share, profit margins
    • Technology: implementation cost, system uptime, ROI on technology investment, time to deploy, and user adoption rates

  3. Skills being tested

    • Traditional: business strategy + financial analysis
    • Technology: bridging business strategy with technical execution—understanding both why and how it will be implemented

Core takeaway: If you recommend a tech solution without quantifying factors like implementation time and total cost, you’re not addressing what interviewers evaluate.

Frameworks the video says you should know (only 3)

  1. PPT framework (People–Process–Technology)

    • People: skills, roles, organizational alignment
    • Process: workflows, bottlenecks, efficiency
    • Technology: systems capabilities and scalability
    • Intended use: primary structure for tech transformation cases

  2. Technology evaluation framework (compare options)

    • Evaluate each option/vendor on:
      • Ability to meet requirements
      • Cost of the project (fully loaded including implementation)
      • Time to launch (how fast you can deploy)

  3. ITIL framework (IT service management across 5 stages)

    • Service strategy
    • Service design
    • Service transition
    • Service operation
    • Continual service improvement
    • Intended meaning: manage IT services in a customer-focused, high-quality, economical way (the video says you don’t need every detail memorized)

Exact six-step process to solve any tech case (start to finish)

  1. Step 1: Understand the case

    • Clarify both:
      • the business objective, and
      • the technical context, including:
        • starting from scratch vs. replacing legacy systems
        • current technology maturity
        • whether the goal is a 3-month solution or a 3-year transformation
    • The video emphasizes these details change the approach.

  2. Step 2: Structure the problem

    • Choose the most relevant framework (from the “only three” stated) and tailor it to the specific case.

  3. Step 3: Kick off the case

    • Candidate-led cases: propose where you’ll start and explain why
    • Interviewer-led cases: follow the interviewer’s direction

  4. Step 4: Solve quantitative problems

    • Tech cases may require ROI calculations for technology investments
    • Before math:
      • lay out your math structure
      • write the actual equation
      • get the interviewer’s approval on the approach
    • Then execute the calculations

  5. Step 5: Answer qualitative questions

    • Brainstorming/trade-offs must be organized
    • Example: “risks of moving to the cloud” should be grouped into:
      • technical risks
      • financial risks
      • organizational risks

  6. Step 6: Deliver a recommendation

    • State the recommendation clearly
    • Provide three supporting reasons
    • Include proposed next steps
    • Example elements referenced by the video:
      • implementation timeline impact on revenue opportunities
      • scalability alignment with growth
      • lower total cost of ownership over a time horizon
      • next steps like validating references and running a proof of concept

The five case types the video says appear repeatedly (practice these)

  1. Digital transformation cases

    • Goal: help a traditional company modernize tech to improve efficiency/customer experience
    • Example: digitize a manufacturing supply chain to improve inventory accuracy and reduce costs
    • Suggested approach: use PPT to assess readiness, identify gaps, and propose phased implementation

  2. Vendor selection cases

    • Goal: compare multiple technology providers
    • Example: a bank choosing between two CRM vendors with different costs and implementation timelines
    • Suggested approach: use the technology evaluation framework (requirements, cost, timeline)

  3. Build vs. buy cases

    • Goal: decide between developing technology internally or purchasing an existing solution
    • Example: retailer launching a mobile app (build in-house vs buy white label)
    • Evaluation factors listed:
      • total cost of ownership
      • time to market
      • customization needs
      • strategic control

  4. Cloud migration cases

    • Goal: evaluate moving infrastructure from on-premise to cloud
    • Example: logistics company considering AWS
    • Factors listed:
      • cost savings
      • scalability
      • security
      • integration complexity
      • vendor lock-in risks

  5. Process automation cases

    • Goal: use technology to eliminate manual work
    • Example: healthcare company spending on manual data entry
    • Evaluation approach listed:
      • calculate cost savings
      • estimate implementation investment
      • quantify accuracy improvements
      • compute payback period

Promotional call-to-action (course)

  • The video promotes a step-by-step case interview course claiming:
    • 82% of students who get an interview land a consulting offer
    • 3,000+ students trained
    • learning “in as little as 7 days” and saving “over 100 hours” of headache

Speakers or sources featured

  • Speaker: “I’m a former Bane manager and interviewer” / unnamed narrator (the video’s host)
  • Companies explicitly mentioned as examples: Accenture, Cognizant, and “Deote” (spelled as given in the subtitles)
  • Named frameworks/standards: ITIL (Information Technology Infrastructure Library)
