Over the past few weeks on #SkillUpSaturday, we’ve explored how to craft the best cover letters and build a standout resume, along with proven strategies on how to apply effectively for jobs that get you noticed. Imagine you’ve now nailed those steps — applications out, callbacks coming in — and it’s time for the main event…

Before you dive into interview prep, it’s important to understand the classic stages of the tech hiring process:

🎯 Typical Stages of the Tech Job Process

1. Online Assessments

   • Aptitude, coding, or subject tests.

   • Purpose: Shortlisting candidates for the next round.

2. Technical Interviews (This Blog: Focus of Today’s Guide!)

   • Coding exercises, data structures, algorithms.

   • Core CS fundamentals: OS, DBMS, Networks, OOP, etc.

   • System design, pair programming, whiteboard or virtual challenges.

3. HR & Managerial Rounds, Salary Negotiations

   • Behavioral/HR questions, company culture fit, leadership/potential assessment.

   • Salary/final negotiations, offer discussions, next steps.

This week’s guide is all about excelling in the Technical Interviews stage — the crucial filter where most candidates either shine or stumble.
Stay tuned: In the next chapters, we’ll tackle the HR/Managerial rounds, behavioral prep, and salary negotiation strategies!

🧩 1. Master Online Assessments & Coding Rounds 🎯

✅ 4. DOs and ❌ DON'Ts of Technical Interviews (Ultimate Guide)

Crushing a technical interview requires substance and style. Master what to say (and what NOT to say).

✅ Top DOs – What to Say & Do

• Research the Company:
  “I’ve researched the company and I’m impressed with X — I’d love your perspective on it.”

• Think Aloud:
  Walk the interviewer through your reasoning and trade-offs.

• Plan Before You Code:
  Outline an approach or pseudo-code first.

• Write Clean, Modular Code:
  Use clear variable names and structure.

• Show Honesty & Adaptability:
  “I’ve been working to improve on X; after taking Y steps, I’ve grown.”

• Ask Insightful Questions:
  “What would success look like in the first 6 months of this role?”

• Showcase Strengths Over Gaps:
  “I’m excited to use my experience to lean into the challenges and learn quickly.”

• Frame Past Setbacks Positively:
  “My previous role ended unexpectedly, but it let me strengthen my skills.”

• Ask About Growth, Not Just Promotion:
  “What does career growth look like here?”

• Express Enthusiasm:
  “I’m looking to use XYZ strengths, and I’m excited about how this role aligns.”

❌ DON’Ts – What to Avoid

• Never Bash Your Previous Boss:
  Say: “I learned a lot in my previous job, but I’m excited for a new challenge now.”

• Don’t Focus Only on Compensation:
  Instead: “I’m excited about this role, and I’d love to understand the comp range.”

• No Excuses for Weak Skills:
  Show growth: “I now use X tools for time management.”

• Never Say You Lack Goals:
  Instead: “My goal is to excel here and grow in X areas long-term.”

• Never Jump Straight into Coding:
  Take time to discuss requirements and edge cases.

• Don’t Parrot Solutions:
  Strive for true understanding, not memorization.

• Never Neglect Fundamentals:
  Basics count, even for senior roles.

• Never Bluff:
  Admit when you don’t know, show willingness to learn.

💡 Pro Interview Tip:
Stay positive, show growth, and approach every answer as an opportunity to shine. Your words can make a great interview unforgettable!
