My argument is not that 'I found interview easy and hence not so bad'. My argument is that in Lyfts case engineering hasnt been the problem with why its business is failing.

Again Engineering is one vector in a company's success but not the only one. It might well make sense for Lyft to pay well for good engineering talent there. Maybe not paying well might have doom'd them much faster.

Your take on OSS is also a naive one . OSS helps in off boarding long term maintenance costs (if the project becomes popular enough) and staves off bit rot. It helps attract talent , creates industry standards etc. Engineering is feature multiplier and for some companies it does make sense to OSS.
