Join this **Interview Simulation** session — to sharpen the skills for both interviews **and** architectural pitches. 💡 How it works The event is split into three parts: 1. **Answers for common behavioral questions** \- at the beginning\, I will read some common interview questions\, explain what they mean\, and give the correct answers\. 2. **Interview Simulation (10 minute rounds)** – One participant acts as the interviewee and answers a round of behavioral and design-focused questions. Each other participant gets to ask him one interview question. 3. **Feedback Round** – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged. 💡You will be asked: * **Behavioral questions** (“Tell me about yourself”, “Describe a challenge you faced...”) * **Technical questions** (based on your tech stack) * **Light design problems** (high-level reasoning, not code) No need to prepare anything in advance — just bring curiosity and an open mind. Feel free to bring your CV if you’d like feedback from others, or share a few words if you’re currently job hunting. If so, we will also brainstorm answers to more common questions that you were asked. Whether you’re preparing for an interview or simply want to grow as a software designer or architect, this session is for you.

Hier triffst du auf Menschen, die verstehen, was es bedeutet, ein Buchprojekt anzugehen – mit all seinen Höhen und Tiefen. Teilnehmerzahl begrenzt. Bring gerne deine Outline, Notizen oder dein Work-in-Progress mit. **Über Text Collective Berlin:** Wir sind eine kreative Schreibcommunity, die regelmäßige Workshops und Lesungen organisiert. 2025 erschien unsere Anthologie "Begegnung zwischen Welten" – wir wissen, wie der Weg von der ersten Idee bis zur gedruckten Veröffentlichung aussieht.

**Come together. Read. Talk about it.** Vielleicht liest du viel und vermisst Gespräche darüber. Vielleicht hast du Lust, neue Menschen kennenzulernen – in einem entspannten, ungezwungenen Rahmen. Lesen verbindet, und genau dafür ist dieser Club gedacht. Dieser *Social Reading Club* ist für Menschen, die gerne lesen und sich genau das wünschen: mehr Zeit dafür – und Raum für Austausch mit anderen, die das genauso fühlen. Wir treffen uns in einem Café am **Platz der Luftbrücke in Kreuzberg**. Nicht als klassischer Buchclub mit Vorgaben oder Pflichtlektüre, sondern als gemeinsames Innehalten: jede\*r liest für sich, egal ob Zeitung, dicker Roman oder Sachbuch. Im eigenen Tempo. Am Ende gibt es Raum für Austausch. Dein Handy kannst du dabei weglegen – ich behalte die Zeit für dich im Blick. **So sieht ein Treffen aus:** → Wir kommen entspannt an, bestellen etwas und richten uns in Ruhe ein. → Der Vormittag besteht aus **einer Leseeinheit**. Wir lesen in Stille – nebeneinander, konzentriert, jede\*r für sich. → Zum Abschluss gibt es ein lockeres Kennenlernen und Austauschen – über das (Buch), was wir gerade lesen, und das, was es bei uns auslöst: Gedanken, Eindrücke, Stellen, die hängen geblieben sind. **ℹ️ Wir sind in dem Café normale Gäste.** Also plane bitte ein, dort etwas zu bestellen. Die Teilnahme selbst ist kostenlos und erfordert keine Vorbereitung. Alles, was du tun musst, ist, etwas zum Lesen mitzubringen. **Kleiner Hinweis:** Das Treffen findet auf Deutsch statt. 🇩🇪 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . **🗓️ Agenda** **11:00 – 11:15 Uhr** Ankommen, Einrichten & etwas bestellen **11:15 – 12:30 Uhr** Stille Leseeinheit (konzentriertes Lesen, jede\*r für sich – gerne Kopfhörer mitbringen, falls es im Café etwas voller wird) **12:30 – 13:30 Uhr** Austausch, Kennenlernen & Ausklang

Curious what we do? Check our [Instagram](https://www.instagram.com/filmmakersandmovienerds/) ♥️ Would you like to meet some like-minded filmmakers? Start a project? Or do you need help with a movie you are currently working on? Are you new in the city and you'd like to meet people tinkering with movies? **Then you should join us!** We meet every Sunday. It’s important to us that we get to know each other in person. To create a community of connected people, work, learn and grow together. For film making you need a crew of reliable people with a positive can-do-attitude. This is the place to find them. Together, we will talk about these topics: * What you are currently working on * What you need help with * What would you like to help with * What you you would like to learn This is event is great for: * filmmakers * movie nerds * writers * camera operators * editors * actors * sound recorders * composers * gaffers * producers We are limiting the amount of people, so we can have a structured introduction and discussion. After that we get together loosely with some drinks and chats. And then we mostly go for dinner with a couple of us. **Important information**: *To sustain and grow this amazing community, we started a member contribution that is due every month. The money we collect is used solely for the purpose of the community. Of course you can come once or twice without contributing to check us out!*

**People Analytics 101: Making Sense of Compensation Data** Compensation data is one of the most widely used and widely misunderstood forms of people analytics. The session will cover where compensation data comes from, including market pricing data, internal payroll data, and benchmarking sources, and how companies think about structuring and analyzing that information. We will explore how compensation data is leveraged to set salary ranges, manage internal equity, support hiring and retention, and align pay with business strategy. A portion of the session will address common data challenges and limitations, such as market noise, inconsistent job matching, and incomplete datasets, while keeping the primary focus on practical use rather than technical depth. The session will also look ahead at where the space is going, including the growing impact of pay transparency laws, expanding pay equity requirements, and emerging regulations in the US and Europe that require organizations to report on gender and pay gaps. The goal is to give attendees a clear mental model for how compensation analytics works today and why getting it right is becoming increasingly critical. (note: we are back at Rev1 this month!) **About Our Speaker** [Alex Moore](https://www.linkedin.com/in/alexscottmoore/) is the founder of [Moore Cooperative](https://moorecooperative.com/), where he advises organizations on compensation strategy, pay equity, and people analytics. His work focuses on helping organizations like the Ohio Supreme Court design, analyze, and communicate compensation systems that are data-informed, defensible, and aligned with organizational goals. Alex lives in Granville, Ohio and has three little kiddos. More info at [cbusdaw.com](https://cbusdaw.com)

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

OWASP is ending use of Meetup, so I built an eventbrite for the event. https://www.eventbrite.com/e/ai-development-risk-case-studies-and-how-agentic-ai-is-the-future-of-appsec-tickets-1981450622150?aff=oddtdtcreator AI is transforming how software is designed, developed, and deployed, dramatically accelerating velocity while introducing new categories of risk. As organizations adopt AI-assisted coding, autonomous agents, and increasingly complex model interactions, traditional application security approaches struggle to keep pace. This talk examines emerging AI-driven risks through real case studies from the field, highlighting issues such as insecure code generation, data-leakage pathways, model manipulation, and evolving supply-chain threats. We will explore how engineering teams must adapt their people, processes, and governance models to secure AI-augmented development workflows effectively. The session will then introduce agentic AI as the next evolution in application security—autonomous systems capable of continuous analysis, multi-step reasoning, and real-time remediation. Attendees will learn how combining agentic AI with modern practices can reduce developer friction, improve coverage, and create a future-ready application security strategy designed for the demands of AI-native software development
