CHAPTERS
- 0:00 – 4:13
Turning feedback into a growth loop (cold open)
Jules opens with a candid take on receiving feedback: outward gratitude even when it stings internally. He frames feedback as a compounding advantage—the more you invite it, the faster you improve.
- •Respond to feedback with genuine appreciation to encourage more of it
- •Internal discomfort is normal; the behavior you show determines future honesty
- •A steady stream of feedback accelerates skill development
- 4:13 – 6:05
Jules’s journey: Haiti to YouTube product lead (Primetime Channels)
Jules shares his unconventional career path—from Haiti to computer science and business school, then medical devices, a failed startup, and finally product leadership in tech. He describes his current work leading YouTube’s Primetime Channels and highlights the challenge and excitement of launching new products at scale.
- •Background across CS, business, medical devices, and entrepreneurship
- •Transitioning into tech product roles after moving to the Bay Area
- •Slack impact in hypergrowth years; now leading at YouTube
- •Primetime Channels: bringing streaming services (and major content) to YouTube
- 6:05 – 7:19
Two practical paths into product management (and why it’s so hard)
Jules and Lenny break down common routes into PM—joining an early startup or transferring internally at an existing company. Jules emphasizes that the first transition is the hardest and often requires creativity and persistence.
- •Path 1: join a startup early and grow into PM responsibilities/title
- •Path 2: switch into product internally by building domain expertise
- •Why PM entry is uniquely difficult: no single standardized pipeline
- •The initial transition matters most—later moves become easier
- 7:19 – 9:01
Becoming Slack’s first growth PM: learning fast through mentors
Jules explains how he landed in a growth role at Slack despite having no growth experience. He credits a learning mindset and deliberate mentorship for quickly shipping impactful onboarding improvements that moved activation metrics.
- •Joined Slack in 2016; growth role was the available door in
- •Used mentors to learn growth frameworks and apply them immediately
- •Shipped new user experience changes (especially mobile) with double-digit impact
- •Lessons from hypergrowth: rapid metric movement and constant milestones
- 9:01 – 12:03
Building community: CodePath and Black Product Managers Network
Jules describes co-founding two nonprofits focused on increasing diversity in tech—CodePath for engineers and Black PMs for product leaders. He shares the origin story of Black PMs, from a small gathering of ~15 people to a community of 1,000+.
- •CodePath trains thousands of students annually for top tech internships/jobs
- •Black PMs provides community and skill-building for PMs and aspiring PMs
- •Started by solving a personal need and helping peers
- •Representation and belonging are core motivators (conferences, speaker visibility)
- 12:03 – 14:52
The PM skill map: IQ skills vs. EQ skills (and when each matters most)
Jules introduces two buckets of PM skills: IQ (execution, product sense, strategy) and EQ (communication, leadership, management). He explains how early career success often comes from sharpening IQ skills, while senior growth increasingly depends on EQ.
- •IQ skills: execution, product sense, strategy—especially critical early on
- •EQ skills: communication, leadership, influencing, managing ambiguity
- •Avoid overwhelm by improving one skill at a time
- •As scope grows, EQ becomes the differentiator
- 14:52 – 18:41
Interviewing as a skill: mock interviews, deliberate practice, and persistence
Jules argues that interview skill is an underrated career lever because it gates access to the environments where you’ll grow fastest. He advocates for dozens of mock interviews and deliberate practice with people who know the bar.
- •Most candidates do zero mock interviews—Jules recommends doing many
- •Deliberate practice beats reading/prepping in your head
- •Interviewing is hard partly because companies rarely provide feedback
- •Persistence matters: Jules interviewed at Google for years before joining
- 18:41 – 20:57
Why interviewing is harder for underrepresented candidates (and how to cope)
Jules explains the added psychological load of interviewing when you don’t see people who look like you—raising stress, self-talk, and belonging concerns. He recommends practice groups and over-preparation so that even a “worst day” performance clears the bar.
- •Extra pressure: bias risk + isolation cues during onsite experiences
- •Cognitive load: belonging doubts while solving complex problems
- •Small practice pods (3–5 people) make prep more consistent and supportive
- •Goal: practice enough that your worst interview is still passable
- 20:57 – 29:45
EQ in practice: self-awareness, stress patterns, and better communication
Jules shares how mentors helped him identify blind spots—like withdrawing under stress or misinterpreting questions as disagreement. He describes how communication evolves from clarity and conciseness to storytelling, audience empathy, and handling Q&A well.
- •Self-awareness requires “a mirror”: mentors, coaches, and reflection
- •Under stress, Jules would go quiet—others misread it as disengagement
- •Reframing Q&A: treat questions as curiosity, ask clarifying follow-ups
- •Senior communication: tailor the story to CEO/CFO/executive audiences
- 29:45 – 35:46
A system for learning any PM skill: define an outcome, work backward, repeat
Jules outlines his personal learning method: pick a concrete outcome that proves mastery, then reverse-engineer the questions, frameworks, and people needed to reach it. He emphasizes fast learning by tapping experts, applying lessons immediately, and iterating in loops.
- •Start with an outcome (e.g., improve activation by X% in 6 months)
- •Generate questions, do light reading to refine them, then talk to experts
- •Apply frameworks in real work with data/research/experimentation
- •Return to mentors with results and new problems—rinse and repeat
- 35:46 – 45:38
Learning by osmosis: reverse-engineer great artifacts and observe the ‘backstage’
Beyond mentorship, Jules learns by studying best-in-class strategy docs, emails, and meeting facilitation. He highlights that seeing iterations—drafts, feedback cycles, and decision tradeoffs—teaches more than only viewing polished final outputs.
- •Collect great artifacts: exec updates, memos, decks, templates
- •Reverse-engineer what makes them work (questions answered, structure, evidence)
- •Observe top performers: sit in meetings, watch presentations and Q&A handling
- •Ask to see the process and iterations, not just the final deliverable
- 45:38 – 51:06
Getting real feedback (especially on EQ): ask specifically, respond gratefully
Jules explains why EQ feedback is hardest to obtain and how to unlock it through trust and precise asks. He shares tactics for eliciting constructive input and stresses that your immediate reaction determines whether people will ever be honest with you again.
- •Make feedback low-risk: build comfort and psychological safety over time
- •Ask specific questions (not “How did it go?”) tied to a skill you’re building
- •Offer self-critique first to invite agreement/disagreement
- •Respond with enthusiastic gratitude to reinforce future candor
- •Seek subjective “how you come across” feedback—the stuff said in calibration rooms
- 51:06 – 55:10
Strengths, weaknesses, and the ‘dial’ concept: double down without overdoing it
Jules shares a mentor’s framework for identifying strengths: what others praise that you dismiss as ‘not a big deal.’ He explains how strengths and weaknesses are often the same trait turned up or down depending on context—and how that realization helps you self-correct.
- •Strength-finding question: what do people say you’re great at that you underrate?
- •Identify the root driver (e.g., curiosity leading to strong questions/networking)
- •Understand the shadow side (e.g., blunt questions can sound junior without context)
- •Think of traits as dials—not binaries—adjust to fit the situation
- 55:10 – 56:27
Mentor hall of fame: the people who shaped Jules’s growth (and what each unlocked)
Jules lists several pivotal mentors and the unique role each played—from growth frameworks to leadership and career transitions. He notes that he arrived in the Bay Area knowing no one, and mentorship networks were built intentionally over time.
- •Examples: Bengali Kaba (growth frameworks), Lorenz Dripsher (blind spots/strengths), Aaron Tighe (Google), Bradley Horowitz (leadership), others
- •Mentors can be external or internal; topic-based or long-term
- •Relationships compound—skills, confidence, and opportunities expand
- •Building a network from scratch is possible but takes sustained effort
- 56:27 – 1:02:37
How to find and approach mentors: smallest ask, then prove you used the advice
Jules breaks down what to look for in a mentor—expertise in a specific skill and the ability to explain it well. His key tactic: avoid big requests upfront; instead, ask a tiny, answerable question and then follow up later with evidence you applied their guidance.
- •Look for: skill mastery + ability/willingness to explain clearly
- •Mentors are everywhere: events, dinners, fundraisers, warm intros, cold outreach
- •Avoid “Can you be my mentor?” and “Can we grab coffee?” as first asks
- •Start with a 2-minute email question; earn the next interaction with follow-through
- •Demonstrate ROI on their time: show outcomes from their advice
- 1:02:37 – 1:05:25
Making mentorship work long-term: specific agendas, note-taking, reciprocity
Jules explains how to sustain mentor relationships without making them feel transactional. He recommends bringing concrete problems, taking careful notes, referencing prior conversations, and actively looking for ways to help mentors in return.
- •Bring a specific, current decision/problem (offers, negotiation, strategy conflict)
- •Take notes and close the loop: “Here’s what I did and what happened”
- •Build a real relationship: remember personal context; continue threads over time
- •Reciprocate—offer help, share candidates, give ground-truth insights
- 1:05:25 – 1:06:58
Closing advice: patience, practice, and treating skill-building like training
Jules closes by normalizing how hard PM growth can feel, especially with so many skills to develop. He emphasizes deliberate practice over passive learning and reminds listeners that EQ skills, in particular, require ongoing training to avoid atrophy.
- •Expect frustration: many skills, slow progress, and occasional setbacks
- •Practice is the unlock—reading alone doesn’t create behavior change
- •EQ growth is long-term and maintenance-based (like fitness)
- •Improvement compounds and eventually separates you from peers
- 1:06:58 – 1:10:26
Lightning round: books, podcasts, entertainment, and an interview question
In a rapid-fire wrap-up, Jules shares his most recommended books, a favorite podcast, and recent media picks. He also reveals an interview question he likes to ask to gauge self-awareness and growth mindset—and notes the real value is in follow-ups.
- •Books: Never Split the Difference; Connect (Carol Robin)
- •Podcast pick: Lex Fridman
- •Movie/TV: Top Gun: Maverick; Never Have I Ever
- •Interview question: “What’s something work-related you’re trying to get better at?”
