Pros

- People you work with become lifelong friends. - You can learn a lot in a very short time. - You can work globally.

Cons

- Top management sees you as dispensable workers, especially if you work in the HQ. Co-Founders also can swear at you. But they are different to global employees because they know they can't grow in the regions like UK and EU with a bad employee reputation. - It's not only that there is a lot of work to do and you work long hours, but they want you to spend even your late nights and the weekends in the office. Even if you don't have work to do, don't have a life and spend every moment in the company. - They pay lower than the industry standart because ''they give bonus'' but then it's very hard to achieve that bonus. It's not only your pay but everything is done with the ''do more with less'' mindset so your computer can break down in the middle of an important call working in an AI company because they refuse to purchase a new one. They won't put AC in the booth so you will sweat if you try to take a call in one of them. - Even if you do good at your job, they always focus on the negatives. You could've done more, take side responsibilities, finish all the projects in your KPIs, etc. - They lure you in with career growth opportunities but in realities there is no roadmap and even if there is a position open and you ask for it, they won't give it to you because of internal balances. Instead of educating the current employees, they try to hire externally and have that position open for months. - Most managers in the HR and especially their Head, have zero industry knowledge because they've only been in one company for 10 years. So they can't give you any good advice and usually make things harder for you. They don't know how to lead people and teams, so everyone is very unhappy. When you give them feedback, they only object and don't change anything.

Pros

Benefits, and Career Growth Opportunities. Company´s growth phase creates opportunities to contribute to building processes, influence change, and have a meaningful impact on the organization.

Cons

The company is going through an important stage of growth and maturity and many processes are currently being standardized and formalized. Employees should be prepared for some evolving workflows and occasional delays in decision-making, especially since many key functions and decisions remain centralized at headquarters in Turkey. Adaptability is important trait to succeed in this Company.

Pros

The company offers a fully remote work model with a highly competitive, above-average salary. As an employee, you are well-equipped with access to high-end development and AI tools to boost your daily productivity. Additionally, they strongly support professional growth by fully reimbursing the expenses for relevant certifications.

Cons

Severe Lack of Work-Life Balance: Management expects you to work up to 14-hour days and weekends just to hit unrealistic KPIs. They have zero respect for personal boundaries or emergencies. I was literally called into a meeting while on annual leave during my mother's surgery. Mobbing is part of the culture, with managers routinely demanding updates at 2 AM. Highly Toxic Environment & Favoritism: The culture is driven by gossip, backstabbing, and nepotism. Merit means nothing; high raises are given strictly based on how well you play office politics with your manager. Many current leaders are only there because of their early tenure and lack the actual skills required to pass a modern senior interview. Unfair Practices & Zero Job Security: The much-promoted "shareowner" program is a manipulative tool to trap employees. It doesn't guarantee safety; people have been given the title only to be unfairly dismissed the very next day for crossing the wrong person. HR Incompetence & Double Standards: Highly inappropriate behavior and severe misconduct (including issues involving intoxication) frequently occur at company events. HR completely turns a blind eye and sweeps these incidents under the rug for high-level management, while regular employees face immediate termination for minor infractions. Manipulated Ratings: The positive reviews you see here and on LinkedIn are largely forced. HR pressures employees into writing them, and there is an unspoken threat of retaliation if you don't comply.
