Pros

Benefits Work from home Latest technologies

Cons

Technical Leadership Gaps: Leaders and managers should possess strong technical expertise in their respective domains to guide their teams effectively and make informed decisions. Excessive Meetings Due to Knowledge Gaps: A lack of technical depth among leaders often results in excessive questioning during meetings, which can consume valuable engineering time and reduce productivity. High Meeting Load for Engineers: Engineers are spending up to four hours daily in meetings, leaving limited time for focused development work. Disrupted Workday Structure: Mornings are heavily occupied with meetings, pushing actual development work to late afternoons or evenings, which affects efficiency and work-life balance. Unbalanced Workload Distribution: Engineers are expected to perform development tasks during the day and handle production support late at night, leading to burnout and reduced morale. Workplace Distractions: Emotional conflicts and interpersonal drama are detracting from core work responsibilities and team focus. Perceived Favoritism in Leadership Decisions: Key decisions appear to be influenced by personal relationships rather than merit, which undermines team trust and motivation. Lack of Accountability Across Teams Teams often engage in blame-shifting and avoid ownership.

Great People, But Culture Took a Turn

Pros

Worked with some incredibly smart and supportive teammates. Flexible work environment and decent benefits. Good opportunities to learn

Cons

Layoffs felt sudden and poorly communicated, creating a lot of anxiety and distrust. The C+4 (quarterly reviews) process became overly focused on numbers, often missing customer realities. Felt more like a performance trap than a constructive review. Management seemed increasingly out of touch with day-to-day customer challenges. Too many meetings that didn’t add value—made it harder to get actual work done.
