1. Work-life balance - you can certainly say goodbye to this concept. Sprints are just formalities.
2. Development team composition - almost all good developers that built the product are gone. Given their history of mistreating employees, new developers are reluctant to join. So they have filled the teams with interns. At the moment interns are running the show.
3. Learning (for experienced > 1 yr) - if you have basic knowledge and experience with enterprise level projects, learning is slow. You will be entangled in a web of issues arising out of bad design, last minute design changes, config issues, production issues (which are way way too frequent). You will be mentoring multiple interns probably. Combine this with the sorry state of implementation of coding best practices. All this leads to stagnation - you will just be applying what you already know, mentoring and fixing issues. Avenues for new learning are quite less and people senior to you are too engrossed in their own workload to transfer their knowledge.
4. Compensation - this company is a real Scrooge. If you are interviewing, negotiate like this is the salary you will have for 4-5 years. Once you join, nothing is assured. They do not give two cents about employee well-being. They will convert the company to a sweatshop if laws permit.
5. Work culture - toxic. CTO is busy micromanaging and turning teams and employees against each other - like a grand scheme of checks and balances of sorts. This gets worse around performance review.
Due to heavy workload, everyone just want to do their quota of work. They write inefficient code which creates havoc in a micro-service environment. You will be fixing pointless issues everyday and wonder at the end of the day if you even learned anything.
6. Vision - I am not writing this as an irresponsible remark but the vision of the company vis a vis employees is to hire cheap labor and work them like a bull. They haven't yet come to grips with the law of dichotomy between quality and quantity. Similarly they are yet to understand the importance of quality code and quality coders in building a durable product.
7. HR Department - although you won't deal with HR dept often, when you will cry tears of blood. Salary comes on time though.
8. Laptops - bad quality laptops that hang a lot.
9. Glassdoor reviews - most positive reviews here are fake. Even I was approached to write a fake one few months back.
