Really bad experience with this firm. Not once but twice. I interviewed with them for the first time in 2019 and then again in early 2020. Both times they wasted my time. Went through multiple rounds, met the hiring manager a couple of times, had calls with him and all this while the feedback from their end was good but no offer in sight. The hiring manager seems to very flaky and whimsical. The second time round, in early 2020, they even asked me for references, saying they need it before making an offer and then gave me a call saying the requirements have changed (in 2 days) and they cannot move ahead with me. I see on GD the reviews of ST London aren't great to begin with and I can see why, if it's driven by this particular manager on the sales side.
