There is a version of mentorship that looks good on paper. Senior figure. Structured meetings. Carefully dispensed wisdom. The kind HR teams can formally label as mentorship.
And then there is what actually happens.
The comment that stops you mid-thought. The junior colleague whose patience exposes your own impatience. The difficult boss who teaches you, through sheer exhaustion, exactly the kind of leader you never want to become. Most professionals, if they think about it honestly, will admit that the people who shaped them most never had “mentor” in their job title and often had no idea they were doing it at all.
The housekeeping staff member who changed leadership forever
Vinod Rai, G-CHRO, Shahi Exports
Early in his career, Vinod Rai had a theory about leadership. Enforce the rules. Maintain discipline. Get results. The harder he pushed, the more the theory failed him.
Meetings went badly. Negotiations stalled. The team grew quieter, and not in a good way.
One evening, after a particularly draining day, Rai sat alone in the cafeteria staring at untouched tea. Most employees had left. An elderly housekeeping staff member named Mewalal walked over, smiled, and said: “When the mind is disturbed, tea gets cold faster.” Then he walked away.
Mewalal had worked at the plant for over 25 years. He cleaned corridors and maintained office spaces. Until that evening, Rai had barely noticed him.
Over the following weeks, Mewalal would occasionally stop by. Sometimes with tea. Sometimes with a quiet question about how the day had gone. Gradually, Rai realised the man observed people more carefully than most managers did. He knew which supervisors frightened employees, which workers were struggling silently, and which leaders people genuinely trusted.
Then came the sentence that changed everything.
“You explain rules correctly,” Mewalal told him one afternoon. “But you explain them like rules. People listen better when they feel you understand their problem first.”
The next morning, Rai left his desk and walked to the shop floor. He listened before he spoke. He had conversations instead of issuing instructions. For the first time, the resistance softened.
Years later, despite serving as a global CHRO, Rai still considers Mewalal one of his most formative mentors. The man whose name never appeared on any organisational chart.
The junior who reshaped a leadership style
Raja Varadarajan, Former CHRO, Vistara
Raja Varadarajan says he has had two kinds of unexpected mentors in his career, instructive and cautionary. Both, he believes, were equally useful.
The instructive one was a team member nearly 15 years younger than him. At the time, Varadarajan found himself frustrated by resistance within his team and slipping into an authoritative style he knew was neither sustainable nor effective.
He noticed that his younger colleague handled the same conflicts differently. Instead of asserting his position, he took time to understand each person’s perspective before offering his own. It was slower. It consistently produced better outcomes.
“That completely shifted my thinking,” Varadarajan says. “I started discussing difficult management situations with him and realised how much more effective empathy could be than authority.”
There were no labels. No formal dynamic. Just observation, and the humility to learn from it.
The cautionary mentor came from the opposite direction: a manager who was deeply insecure and exhausting to work with. But the experience forced him to develop resilience, emotional boundaries, and a clearer sense of the leader he wanted to become.
Almost every professional has one such manager in their past. The ones who describe the experience with generosity usually learned something from it that comfort could never have taught them.
The youngest person in the room
Sujiv Nair, CHRO, MS Laboratories
Before an important presentation early in his career, Sujiv Nair did what careful professionals do. He perfected the slides, rehearsed the answers, and polished every line.
After the mock run-through, one of the youngest people in the room said something he did not expect.
“You know the content really well. But you sound like you’re trying to impress people instead of talking to them.”
Nair was briefly taken aback. Then he realised it was true.
“I was so focused on appearing competent,” he says, “that I had forgotten the human side of communication.”
He stopped treating presentations as performances and started treating them as conversations. The shift was small in theory and significant in practice.
“Some of the best career advice I received came from someone with far less experience than me,” he reflects. “Wisdom and seniority are not the same thing.”
The mentors nobody officially calls mentors
Workplaces tend to direct people upward for learning. Towards bosses, CXOs, industry veterans. The assumption is that authority and insight travel together.
Quite often they do not.
Some of the most useful lessons arrive sideways or from below: from a junior colleague who is honest without agenda, a peer who models something worth learning from, or a support staff member who has spent decades quietly observing how people behave when things go wrong.
What these mentors share is that they appear without performance. No formal agenda. No carefully curated philosophy. Just an ordinary moment that changes how someone leads, listens, or sees people.
Growth, it turns out, is rarely hierarchical. The proof is usually standing somewhere nobody thought to look.
