Wipro Technical Leader interview questions

It took more than 4 months to hire a professional which is very long. Resume was sent in May and haven't finalized the offer letter yet in September end. This is very long and doesn't look good to keep a candidate without giving the actual cause for delay.

very good interms of management and worklife balance stats, career growth, leave and health policy. multiple projects, but we can switch only after serving 18 months after joining in any role/project
