Do you hire developers based on technical skills alone? It could be costing you.  Many companies make this mistake, believing that if a developer can code well, they’ll automatically thrive in the team. But this is not always the case. I have a client in Krakow who specifically hires Java Engineers who can have a “normal conversation" about software, clean code practices, and general life. But most importantly someone he can get along with. If they can do that, he’s usually ready to hire them. However, if they don’t fit culturally, it doesn’t matter if they’ve coded at Google, have an Oxbridge education, or have a long list of technical achievements. They won’t get the job. This is also not unique. According to Leaders.com, approximately 80% of employers take personality into account when making hiring decisions. Also research from Harvard Business Review found that 40-60% of hiring managers admit to hiring candidates who resemble them in terms of background, values, or attitudes. None of this mentions their skills. The ability to mesh with the team and collaborate is non-negotiable. Some people picture developers as introverted hackers, coding away in dark rooms, surrounded by empty energy drink cans. The stereotype that developers don’t need social skills in my opinion, comes from how they’re portrayed in Hollywood (Die Hard 4 was what came to mind when writing this). In reality, developers are part of cross-functional teams. They interact with product managers, designers, and other stakeholders daily. They need to explain complex ideas, collaborate on solutions, and contribute to the team’s overall culture. A developer who can’t work well with others or communicate effectively can disrupt workflows, no matter how technically gifted they are. It’s like having the most advanced software that no one knows how to use. What’s the point? The best hires are those who fit into your culture and can contribute to the team dynamic - not just those who can write the cleanest code. So if you’re only hiring based on technical skills, you might be missing out on your most valuable assets: collaboration, communication, and cultural fit. Skills get you in the door, but culture fit keeps you there. Do you take culture fit into account when hiring engineers?  #SoftwareEngineering #PolandTech #TechRecruitment #PolandJobs #CultureFit #DeveloperLife #WorkplaceCulture #TechRecruitment

Are your software engineers' salaries aligned with today's market? Since 2020, salaries in Poland have gone from predictable to, well, unpredictable. I’ll never forget placing a Senior Ruby Developer for 13.5k PLN/month (B2B) back then. Fast forward to today, and that figure feels like a distant memory.Figuring out what to pay engineers isn’t as easy as averaging job board numbers (I wish it were). If you’re grappling with this challenge, here are three proven strategies to help you find the sweet spot: 1️⃣ Leverage Your Recent Hires Use data from the last 6 months. - Focus on salaries from closed contracts - interview figures only tell half the story. - How often have candidates been willing to commit to your offers? - Numbers from signed agreements paint the most reliable picture. 2️⃣ Listen to Engineer Feedback - Track how candidates respond to your offers: Are your salaries getting a thumbs-up or silence? - Does raising your range increase applications? - How challenging is it to close candidates at the current rate? 3️⃣ Consult a Niche Recruitment Partner - They’re in touch with engineers daily and know what works now- not last quarter. - They track salary trends across clients and can pinpoint real-time benchmarks. - Best of all? They will share this info for free.

Next AWS User Group Wrocław meetup in a week (24.04.2024). 📅 24.04.2024 ⌚ 18:00 📍 Wędrówki Pub: https://lnkd.in/eeYukrXZ First of all, thank you ALGOTEQUE Innovation Hub for sponsoring our event! :) 🎤 Speakers: 🔭 Marcin Sodkiewicz (me) I am going to talk about #opentelemetry in my talk titled "Observability on AWS & OpenTelemetry". It's talk on the 300 level, but don't worry, I am going to cover all areas, and even if you are new to a whole concept I think you should understand everything. This is also a great opportunity to discuss your experiences with #opentelemetry. 📟 Grzegorz Kalwig: "Serverless is above limits? Our Path to production database cluster" If you don't know about it - Grzegorz is on a road tour with that talk as I believe I saw that he presented that material in many User Groups already. It means that his material is polished and he should be able to answer all your questions about Aurora Serverless v2. Super interesting and important topic, so stop by and make notes :) We are still part of JetBrains Community Support program. So we are going to give away some coupons for free access to IDE of your choice for a whole year.

📢 Huge shoutout to Michael for the Apropo intro! It's made a real difference in how I approach client projects. 🔥 Apropo has been a game-changer for client engagement. 🖇 The proposals look fantastic (say goodbye to spreadsheets!), which builds trust and satisfies clients' curiosity – They love the ability to drill down into tasks and see the details. I haven't had a single client who wasn't happy  with this level of transparency! 👨‍💻 From a developer's perspective, Apropo makes creating estimates a breeze. The collaborative features allow my entire team to work together in real time, which saves a ton of time and improves brainstorming sessions.   ✨ All this contributes to the quality of the final proposal, making it stand out from the competition. 💪 This level of transparency and collaboration is essential in today's software development landscape. 🥇 Apropo has revolutionized the way I create proposals and I highly recommend it! #apropo #geeknauts #clientengagement #softwaredevelopment #projectmanagement #proposalwriting #collaboration #saas
