Pros
I can't find any reason why you would like to work at eBay in 2019. Work life balance can be good (depends on your team). In the past, it was a stable employer. However there have been multiple layoffs in last 2-3 years.
Cons
Sub-par pay (check paysa for comparison with other tech companies), highly political culture . In engineering, most employees are Asian or southeast asian and they decide culture of the team (for good or bad). For last 2-3 years, there have been layoffs every half year . Management is looking for short term gains and is changing direction every other quarter. One of my former colleague (who got promoted last year) was laid off when she was on maternity leave (see the culture point above mentioned) , was given severance package and asked not to come back from maternity leave (looked like discrimination). If you are not working on payments 2.0 (highly publicized in techcrunch ) or checkout, just leave the company. Anyone else apart from those 2 teams can get laid off. I left it at the right time and I wouldn't recommend it to any of my friends now. Sad to see (once a) great company going downhill .
