ByteDance

• Data-driven. The new product features came from data analytics. The product features were experimented with using A/B tests.

Features were released to all users as long as they increased critical product artifacts (e.g., user visits, user retention).

• Good infrastructures. Many infrastructures improved efficiency, such as A/B testing, settings, a rich amount of 2nd-party components, and DevOps.

• Good documentation. I didn't love documenting until I entered this company. You could easily find answers to problems by simply searching the documents. The Lark Document was a great product.

• Talent and hard-working coworkers. Most of the coworkers were friendly, talented, and hard-working, even the graduates. You always got motivated working with them.

• Heavy workload. The working hours were mostly from 10:30 A.M. to 10:30 P.M. I always left the office at 10:30 P.M. because there were so many tasks to finish every day. The company offered 3 meals, so you didn't have to leave the office.

• Lack of manpower all the time. I often felt overwhelmed but didn't have coworkers to delegate some tasks to. In hiring new employees, HR didn't help much; we were on our own.

• Hard to finish work at the office. Distractions from meetings, instant chats, and coworkers all the time meant I sometimes got started work after everyone left the office at night.
