Lessons from mentoring 1,500 digital marketers

I spent three years teaching digital marketing at IIDE, plus guest sessions at Hinduja, Thakur and Pillai colleges. That’s 38 cohorts, roughly 1,500 students, and a lot of 21-year-olds asking “sir, which course should I take next?”

This is what I tell them, including the parts nobody else does.

The students who build real careers don’t look like this on Day 1. They get there by Year 5, after years of the boring work nobody on LinkedIn talks about.

The marketers who win can read

I mean read, not “consume content.” A 4,000-word essay, a book on cognitive bias, a dull B2B case study. The job is pattern recognition, and you can’t learn to spot patterns from 30-second clips.

The best predictor of which of my students reach a senior role by year 3 is whether they read. Their tool stack matters much less.

I’ve tracked this informally across cohorts. The students who read actual books, long-form articles, company annual reports and competitor analyses develop an instinct for strategy that tool-first students never pick up. They can look at a campaign and say “this won’t work because the positioning is off” before the first report comes in. A YouTube tutorial won’t teach you that.

What I recommend my students read:

• One marketing book per quarter (skip the “growth hacking” books and read about psychology, persuasion and decision-making)
• The Stratechery newsletter (Ben Thompson), which teaches you to think about business models
• Company earnings calls and investor presentations, which show you how businesses actually make money
• Competitor websites with a critical eye: “what are they testing? what’s their funnel? where’s the friction?”

What I tell them to stop reading:

• “Top 10 digital marketing trends” listicles
• Anything that starts with “This ONE trick will…”
• Thread bros on X (formerly Twitter) rehashing other people’s case studies

Tools are commodities

Every cohort, students arrive nervous about which tools to “master.” Google Ads? SEMrush? HubSpot? GA4?

Any motivated person learns a tool in two weeks. What takes a decade is taste: knowing what not to do, when to wait, and when to kill a campaign that’s “almost working.”

I’ve watched the tool fashion change three times in the last five years:

• 2021: “Master Facebook Ads Manager, that’s where the money is”
• 2023: “Learn ChatGPT, it’ll replace copywriters”
• 2025: “Build AI agents, that’s the future”

The students who chased each wave are now mediocre at three things. The ones who spent those years getting really good at understanding customer behaviour, on whatever platform, are getting ₹12–18 lakh offers.

The toolkit that actually matters:

• Critical thinking (can you honestly judge whether a tactic is working?)
• Writing (can you explain a complex idea in 200 clear words?)
• Basic data literacy (can you read a spreadsheet and spot a trend without panicking?)
• Patience (can you run a campaign for 3 months before judging it?)

You can learn everything else (specific platforms, ad formats, analytics dashboards) on the job.

The unsexy careers compound

The students with the wildest LinkedIn careers (founder at 23, agency at 24, advisor at 25) often plateau by 28. They’ve done a bit of everything and mastered nothing, and their network is wide but shallow. When the market tightens, they struggle because they can’t point to deep expertise in anything.

The ones who quietly went deep at one company for 4 years are running marketing departments now. They know one business inside out. They’ve seen campaigns through full cycles of launch, optimisation, scaling, decline and pivot, and that repetition gave them judgment.

Keeping your options open feels like wealth. Depth is the thing that actually pays.

A pattern I see in Mumbai specifically: the city’s startup scene puts heavy pressure on you to “do your own thing” by 25. Students see founders on Instagram and assume the path is learn marketing → freelance for 6 months → start an agency → scale. In reality, 90% of those agencies close within 2 years. The students who joined a mid-stage D2C brand or a good agency as employee #3 and stayed for 3 years have better careers, skills and networks.

The placement reality nobody discusses

At IIDE, we tracked placements. The quality of those placements varied enormously, though, and the difference came down to things students don’t want to hear.

Students who get the best placements:

• Built a portfolio during the course (real projects, not assignments)
• Had a specialisation they could explain (“I do SEO for e-commerce” vs “I do digital marketing”)
• Could present their work clearly in 5 minutes
• Read widely enough to have opinions about the industry

Students who struggle with placement:

• Completed the course but never practised outside of class
• Can list tools on their resume but can’t explain what they’d do with them
• Apply to 200 jobs with the same generic resume
• Don’t have a single piece of published work (blog post, case study, portfolio site) they can point to

The fix is simple: build something real during the course. Audit a friend’s website. Run a ₹5,000 Google Ads campaign for a family business. Write 5 blog posts about what you learned. When the interviewer asks “what have you done?”, you need more than “I completed the certification.”

What I’d tell 21-year-old me

If I could go back and talk to myself at the start, when I was nervous, unsure which “niche” to pick and overwhelmed by how much there was to learn:

1. Pick one skill and go embarrassingly deep. “Digital marketing” is a department. Pick a skill instead: SEO, paid media, email marketing or analytics. Go deeper than anyone else your age. The generalist role comes later, after you have one area of real expertise.

2. Get a job at a company that sells something boring. SaaS, logistics, insurance, B2B manufacturing. Their marketing problems are harder and more interesting than D2C Instagram, and you’ll learn more in 2 years than most people learn in 5 at a trendy brand.

3. Write in public. A blog, LinkedIn posts, a newsletter. Writing forces you to think clearly, and the archive becomes your resume. Five years from now, the 30 blog posts you wrote while learning will be worth more than any certificate.

4. Find one mentor, not five. You want one person who knows your work, gives honest feedback and answers when you’re stuck. Five “mentors” you met at a networking event and send generic “catch-up?” messages to won’t do that. Depth beats breadth in relationships too.

My one-line advice

When students ask me for one piece of advice, I always say the same thing:

Pick the boring problem nobody else wants. Solve it for a year. You won’t have competition.

Skip “AI marketing,” “growth hacking” and “personal branding.” Pick the problem that makes your classmates yawn: site speed optimisation, email deliverability, GA4 implementation, WordPress security, local SEO for small businesses.

There’s a huge market for people who can solve boring, specific problems, and never enough of them. The market for generalist “digital marketers” is oversaturated and gets more crowded every year.

Pick the boring problem, solve it better than anyone else, and keep at it for a decade.
