It's a 3-stage interview process. The first stage (l0) is introductory, where they review your resume and ask about your skills and some basic questions. Then there's a technical interview (l1). After that, an HR round (l2). Finally, a Data Structures and Algorithms (DSA) round (l3). This is for the bond interview process.

Behavioral Technical
I had a pre-screening call with HR and then got scheduled for the first round within 2 days. A developer conducted the first round, asking general JavaScript questions. Two days later, HR called for the second round, which was with a manager from Delhi. This manager was quite unprofessional, frequently talking to colleagues, taking calls, muting himself, and making faces. The questions were excessively detailed for the offered compensation. Not recommended.
