Spero Labs Reviews 13

Sam is exceptional when it comes to career support. He is very knowledgeable and really detailed when curating a personal plan of action. I don't know if I would have been as successful in my job search without his resume support and interview preps. His holistic approach and insights was exactly what I needed.
I highly recommend Sam for anyone going through a career shift.

I am very grateful to have met and worked with Sam. He saw potential in me when I couldn't and worked with me to bring it to fruition. Despite having mentored people in every stage of their careers, he will sit down with you and focus on growing your career with a level of personal detail I have never seen in anyone before.

Sam provides deep and thoughtful insights on what's going on inside a recruiter's mind and how to create a clear and coherent narrative. He challenges you to think bigger about your own potential and gives you the practical tools needed to get there. After working with Sam, I am more confident in myself, and approach my career with better clarity and direction.

What sets Sam apart is his genuine investment into his mentees. He doesn't just offer general advice but partners with you to discover every avenue of growth and pushes you to become the best version of yourself.

Sam is a pleasure to work with. The perspective he brings is incredibly refreshing — he focuses directly on what actually gets results and cuts through unnecessary noise.

He provides clear strategy and strong mental models around what matters in a job search, what is genuinely beneficial, and what tends to waste time or even work against you. His guidance is direct, practical, and grounded in real experience.

If you’re looking for honest, powerful feedback and structured direction rather than generic advice, Sam delivers.

I am super grateful for the support and guidance Sam provided. From helping me refine my resume and stand out as a candidate, to sharpening my technical and behavioural interview skills, the advice he gave was always thoughtful and practical. He helped me craft a clear narrative around my experience that set me apart from other applicants and played a key role in moving me forward through interview rounds. I would not have had the same confidence or clarity in my approach without Sam’s help, and I would highly recommend him to anyone navigating their next role.

Sam is amazing. He gave me a completely new perspective on how to frame the narrative around my profile and my resume. He also gave me a holistic view of what a strong profile looks like across my resume, LinkedIn, and GitHub.

His “less is more” approach made a real difference, my hit rate improved a lot after I implemented his advice. He goes into the details, explains the reasoning behind each change, and how recruiters tend to perceive it in industry. He also says the quiet part out loud, you get a clear sense of how a recruiter thinks when reviewing a profile, including things they don’t openly share. I’ve attended over 50 hiring events, but I’ve never gotten as much real/ unfiltered insight into how recruiters actually perceive a resume as I did with Sam.

I am more than satisfied with Sam's services. Sam refined my resume, narrative, and interview skills top to bottom. He continued to coach me through an intense job search with technical, behavioral, and phone screen interviews and even motivated me through some tough times.

Sam gives great advice on everything involved in the process of landing a good career in tech, whether it is resume writing or online assessment and interview preparation. When I was searching for a new job, he gave helpful tips on improving my resume, and when I was preparing for technical assessments and interviews, he pointed me towards the most targeted resources for brushing up on the relevant knowledge and gaining practice. Highly recommend to anyone looking to land their dream job in tech!

Sam's mentorship has been one of the most enlightening experiences in my job search. He spent so much of his time with me to understand my specific situation. He also understood how to get exactly where I wanted to be. Not only did he help regularly give feedback on my resume to continually improve, the mock interviews gave me the practice I needed to go into interviews speaking confidently and stop my mind from going blank when the pressure was on.

What stood out most was how much Sam genuinely cared. It always felt super personal. He was as invested in my success as I was and it showed in the quality of feedback and guidance he gave. Thanks to his help, I landed a role at Adobe.

If you're serious about your search or just want to level up and want someone in your corner who actually cares, I'd highly recommend reaching out to Sam. He will surely reach back! He will be with you all the way, and teach you how best to succeed.

Sam gave me great tips for improving my resume and strategies to put my best foot forward in coding interviews.

He's very helpful and would recommend him to anyone looking for guidance on how to break into the computer science field!

I’ve known Sam for a couple years now and he’s been one of the most helpful mentors I’ve had while navigating software engineering job searches. His resume reviews are incredibly thorough: he doesn’t just fix wording, he helps you frame your work in a way that’s clear, impact-focused, and actually aligns with what recruiters and hiring managers look for.

For interview prep, his mock interviews feel realistic and targeted. He’s great at spotting patterns (where your explanations get fuzzy, where you’re skipping key details, how you’re communicating tradeoffs) and giving feedback that’s specific enough to improve immediately. Beyond that, he genuinely cares and consistently shows up. If you’re serious about landing a SWE role and want mentorship that’s both kind and high standards, Sam is the guy to go to.

I reached out to Sam for resume help, but I left with a completely new career trajectory. He was instrumental in helping me format a resume that passes ATS and frames my experience as a cohesive narrative.

More importantly, Sam taught me to treat my career like a long-term investment. He guided me through pivotal education decisions and helped me plant seeds that are starting to pay off in huge ways. He hasn’t just coached me; he has transformed the way I think about and approach software engineering. I am now more confident, optimistic, and have a clear roadmap for where I’m going

Sam’s been an incredible mentor who has been my guiding star. He didn’t give generic advice. We had real discussions about what I wanted to achieve and why it mattered to me, and he used that to steer me in the right direction. He took the time to understand my situation, where I was starting from, what I was aiming for, and what was realistically going to move the needle. Based on that, he helped me build a clear plan without fluff, with the right priorities and sequence, so I always knew what to focus on next.

He was also very impactful in the education decisions I made along the way. He helped me think through my options, weigh tradeoffs, and choose a path that actually supported my long term goals. Those decisions ended up making a real difference in my growth and helped me become a better software engineer.

What made the biggest difference was how involved he was and how much he helped shape me into a stronger software engineer. He pushed me to think more clearly, communicate more directly, and approach problems in a more structured way. When I was unsure, he would ask the right questions, break things down, and help me make decisions rather than getting stuck. Over time, I started approaching learning and building the way a strong engineer should: focusing on fundamentals, being consistent, and improving step by step.

He reviewed my resume in detail and gave feedback that was specific and actionable. Sam also helped me refine my LinkedIn profile. His recommendations directly led to better results, including more interviews from roles I applied to through LinkedIn. Overall, it was a drastic improvement because his advice was focused on my specific goals.

Sam is honest, direct, and genuinely invested in helping you succeed. He has been way more than a mentor. Over time it felt less like coaching and more like having someone who actually cares and wants to see you win.

I highly recommend Sam to anyone looking to advance in software engineering or beyond.

I had a great experience working with Sam Lee at Spero Labs. I originally reached out for help with my resume, but it quickly turned into much more than that.

Sam took the time to really understand my background and goals instead of just editing bullet points. He helped me reframe my experience so it actually told a clear story and made sense to recruiters and hiring managers. The mock interviews were especially helpful, they felt realistic and pushed me to think on my feet, and the feedback I got after each session was honest and practical.

What I appreciated most was how personal the whole process felt. It never felt generic or rushed. I always felt like Sam genuinely cared about helping me improve, not just checking a box.

Because of the preparation and guidance I got through Spero Labs, I went into my interviews way more confident and ended up landing a role at JPMorgan Chase. I’d definitely recommend Sam to anyone who’s serious about leveling up their resume and interview skills.
